Tbh you are the best SAT tutor youtube I have ever seen and I spend a lot of time looking for help on SAT here on youtube. I found you about 2 weeks to my exam and have watched several of your videos.. I will be taking the exam tomorrow and I just want to say Thank you so much. I can't believe I paid $50/hour for the informations you give out for free. I am sharing this with all my friends and the juniors who are going to be taking the SAT next year. You deserve more subscribers and I wish I found you earlier.
b2 - 4ac < 0 (-4)2 - (4 x 2 x -t) < 0 16 - (-8t) < 0 16 + 8t < 0 8t < 0 -16 8t < -16 t < -2 So option A as it is only less than -2. Anyway thank you for the video
I needed to review my math because my SAT is tommorow and I have to say that your review videos are the most engaging and easy to understand ones that I have seen so far-- almost too easy to understand lol.
My math score was 550 . After watching your videos I got 680. Thank you so much! Want to get 800 and I have 2.5 month ) Where can I get more of your videos?
you make math fun through being understandable. god bless sal khan, but even he couldn't make this comprehensible for me (smol brain.) fortunately, you break everything down so wonderfully even i can understand it. have a wonderful day!
Hi sir, the world needs tutors like you, The SAT analyzer which you have kept free for now has helped me a lot. I wanted to ask whether you are planning to keep math accelerator free for even one week.
you could also think about the last problem conceptually but it's more difficult. if you move "t" over to the left (2x^2 -4x - t = 0) you know t has to be negative to create a positive "c" value, since the graph opens upwards due to the positive "a" value; this would allow there to be no x-intercepts. out of answer choices "a" and "b," without doing any calculations "a" is a better choice because it's higher up and therefore less likely to dip below the x-intercept, which would give the quadratic solutions. thanks for the vid :)
@@JohnSATyour last problem in this video is done wrong, as other ppl have noted in the comments. u didnt move t to the other side of the equation to make it the general form. the answer is the negative version of what u got
Can you please make a video explaining the concept “calculating mean, median, mode, and range of data, and understand how these, along with standard deviation, affect the shape, center, and spread of data”?
For the last problem we can easily solve it, if we use simple calculus. 2x^2 - 4x = t can be written as 2x^2 - 4x - t = 0 derivative of the expression above is 4x - 4, since t is a constant. we can find the critical point by finding the root of 4x - 4 = 0 and the critical point is at x = 1 insert 1 in 2x^2 - 4x - t > 0 solve for t and that will give you t < -2
Bro your amazing!!!! also kinda I need help with the English section and RUclips channels or website you recommend !! Again your math sessions are amazing I saw the whole playlist and it's great!!!!
For the question that you used the quadratic equation. Did you need to simplify it first by taking out the 3. Or can I just plug the original numbers that they give me in the quadratic equation. Amazing vid btw. Helped a lot
for the problem you're solving at 8:12 -- would i always need to simplify the equation from like 3x^2+12x+6 to x^2+4x+2 before plugging it into the quadratic formula?
Hi, I want to buy your course but the thing is that I'm a foreigner ",i have never taken sat before and my math score is 250 and you said your course can help only students who have above 400 points Should I purchase your course If not how can I improve my
@ 8:10 how can we simplify all of the 2s? the denominator would become 1 on simplification and 4 in numerator would become 2. so how can we simplify it someone help asap
Hi Sir, I would suggest you to put your face cam big at the start of the video and maybe towards the end. In the middle it is best for you to show the question and work as big as possible for people using smaller devices.
That's correct! The "t" I plugged @ 11:51 should've been "-t" So the sign would be flipped and the correct answer would be A. Thanks for pointing it out
no. b is -16, so -(-16)/2 = 8. 2 negative signs multiplied make a positive. he did the last problem wrong though in the video because he didnt move t to the other side of the equation to resemble the general form where c would be -1t.
remake this video lmao, too many mistakes for beginners. I'm just doing this to revisit mistakes and some people might not know the "answers" as opposed to what you wrote down.

finally someone answered like me , i thought i was wrong !
i also thought the same
Lol I noticed the mistake he did too but for a sec I thought I was wrong.... Thanks for commenting
thanks so much i stared at this for way too long thinking I was dumb
I spent hundreds of dollars on sat prepping and your free RUclips video helped me more than any of my tutors 😭
This guy is the bomb fr

Thanks a lot for this crucial lesson. It means a lot. My exam is tomorrow, hope to ace it and make you proud.💪💪☺
you are the best teacher, currenty i am having SAT courses but teachers dont like u, your method is amazing
thank you!
Bruv Finding roots part 4
the answer is -3 .You forgot the sign of t which is -t: so it will urn out to be, (-4)^2-4*2*(-t)
❤
I feel like 3. Number of roots would have been more easily solved by simplifying 16-8t

so your saying that -3 is the answer right, thats what i got and im so confused
To solve for x in a quadratic equation, just use your calculator to input mode 5, 3 and add your values
And your calculator will solve it for u
I am so lucky cuz I found your channel before my test day ... Thanks a lot 😍
Thank you John🤝🏿, currently reviewing and revising 1 week before my Test date😅. Coming in clutch fr
Best of luck on December!
me too!
I love your videos man!! thank you! Can you please do a videos on "isolating complex quantaties" ?
not sure what that is, but it could be covered under the complex numbers video in the channel.
Thank you so much for these videos. They are super helpful. Please can you make a short video on factoring 🙏?
How do I know if the discriminant is 0, =0. Also the video was very helpful keep it up !!
You can calculate the discriminant using its formula (b^2-4ac) - If it's still confusing, the private lecture will go over it super in depth.
@@JohnSATyour last problem in this video is done wrong, as other ppl have noted in the comments. u didnt move t to the other side of the equation to make it the general form. the answer is the negative version of what u got
@@CharlesGrube-p7g You're correct. It's addressed in the pinned comment.
For finding roots just use mode 5 ,3 in the calculator
Insanely helpful video my SAT is in December tysm
hy thanks soo much for making these amazing videos. Could you please do a video about linear equations
Sure! Added to the list
@@JohnSAT can you link me the video please I can't find it
AMAZING!!
Glad it helped 😁😁😁
it will be super helpful if you could make a video about factoring
thank you this lesson is very usefull for me
omggg thanks you saved my life 😅❤
❤
Please make a video for super fast factors of a quadratic equation
Hey, could you please do a vid about lines? Thanks
Can you please make a video explaining the concept “calculating mean, median, mode, and range of data, and understand how these, along with standard deviation, affect the shape, center, and spread of data”?
Lines is coming up next week!
Man that's a lot of material haha. I will add it to the list and make a video on it soon
your videos are so helpful thank you so much for your efforts I really really appreciate it
😀 😀 😀
Maybe,you did wrong to find value of "t". It'll be "- 3" not "3". Thank you.
Nevertheless, appreciate to make this kind of video.,❤️
Thank you so much !!!! Amazing video
I love this man
for the discriminate question, what if the question says the parabola has one or two solutions, then what would you set your inequality to?
it will never say that.
Can u show how u factored the equation?
Now that Desmos is available on the SAT, we can just plug in each given equation to easily find roots XD
thank you very much❤
Can you make another video about interpreting non lineare expression?
😭why didnt i find you sooner ...no it didnt even take me welks but 3 hrs to boost my basics in math because of yoy
brother I appreciate your videos but have to add that you make a lot of silly mistakes not only in this video but on your other videos as well.
Thank you SO MUCH ❤
I hope you are doing well
For the last problem
we can easily solve it, if we use simple calculus.
2x^2 - 4x = t can be written as 2x^2 - 4x - t = 0
derivative of the expression above is 4x - 4, since t is a constant.
we can find the critical point by finding the root of 4x - 4 = 0
and the critical point is at x = 1
insert 1 in 2x^2 - 4x - t > 0
solve for t and that will give you t < -2
one of, if not the most efficient tutor on youtube for the math sat 😭 thank you 🫶
Thank you from Brazil!
Welcome!!

Thanks man! I heard Seberson Method is pretty good for the reading section. Check it out ;)
Hey, can there be more videos on parabola questions. Still face a little difficulty in solving slope questions
For the question that you used the quadratic equation. Did you need to simplify it first by taking out the 3. Or can I just plug the original numbers that they give me in the quadratic equation. Amazing vid btw. Helped a lot
it makes it way easier to j take out the 3
In finding roots pt2 isn’t the a 3 bc it’s the coefficient of the x^2

Hi JJ, what gadget do you use to present your writing on the screen?
Thank you, this was helpful
8:21 you forgot to distribute the 3 to the equation.... or is it that im wrong just add correct me if im wrong
for the problem you're solving at 8:12 -- would i always need to simplify the equation from like 3x^2+12x+6 to x^2+4x+2 before plugging it into the quadratic formula?
you don't have to, but doing so will keep the numbers small & simple for the quad formula

Hi Sir, I would suggest you to put your face cam big at the start of the video and maybe towards the end. In the middle it is best for you to show the question and work as big as possible for people using smaller devices.
what device are you watching it from?
I just did the #13 that you did but the scoring sheet says the answer is A?
That's correct! The "t" I plugged @ 11:51 should've been "-t"
So the sign would be flipped and the correct answer would be A. Thanks for pointing it out

LMFAOO THE SOUND EFFECTS
for the sum of roots isnt the answer suppose to be -8 since the formula is -b/a
no. b is -16, so -(-16)/2 = 8. 2 negative signs multiplied make a positive. he did the last problem wrong though in the video because he didnt move t to the other side of the equation to resemble the general form where c would be -1t.
