Once again, this is a super video, showing how doable it is to attain high SAT scores! Question on #18: The Discriminant describes how the parabola itself intersects the x-axis. It would NOT describe how the line and parabola intersect. The line and the parabola have to hit at 2 points, but can't those points be irrational? If you plug and chug the values for k into your new equation you see that they are irrational for k=3, but they do intersect. k=0 gives x^2 = -1. Thanks again for your great work!
in 15 the amount of height is z, which is what we are trying to find. Therefore, w is the age of the tree which when multiplied by 4/3 will give us the height of the tree. Hopefully, that made sense. 🙂
Because each factor corresponds to the variable positions of a quadriceps equation. The x squared would correspond to the x squred, the kx would then correspond to the x- variable factor of a quadric, and then we would have the -k+1 left over, in which would finally correspond to the c variable in the quadric (the constant variable). Hope this helps.
please do more of these
Will do.
For me I don’t know why no one supports you I will try to help you bro I am from Egypt and I will help you in my corse to share your videos
Thank you for the support my friend!!

You're very welcome, and thank you for your comments!!
Love from Maths and fan ☺ SAT
Thank you!
Thank you for this, I jus gotta memorize these concepts
Keep working hard and using all available online resources to work through the problems!
thank you so much bro!
Can you please do the released qas tests r/sat in reddit has links to all of them
Yes I'll do more for sure.
@@ScalarLearning thank u so much this and the critical concept series are my favourite
EXCELLENT
Thank you! Cheers!
You explain rates so well, please could you do a video on them in more detail?
Like ratio, proportions, scale ect
Can you please where do you get these real tests from because I nearly finished all the practice tests and thank you for the great video.
You can gain access to practice test, study guides, and question-and-answers through College Board!
can you please do college panda math chapters and overview after
I've done so many of those already.
Scalar Learning no not the practice test the actual workbook
Bro part 3 of critical concepts?

Hey what are ur Roughly Top 5 Math Resources Recommendations , and which ones do u recommend not going near or not very Helpful ?!
Do QAS! Do KA but don't take it seriously since most question types don't appear on the real thing.
(This is math)
Scalar Learning always!
All the ones I do on this channel, but the real tests are the best.
Hi what’s the name of the answer choice D function in Q23 haha looks pretty weird
It's a step function
What QAS would you consider to have the hardest maths section?
specifically i found sat maths question with the titled "school day 2022 may " to be the hardest the normal version are a breeze comparatively
I tried to find this in collegeboard but could not fond
Try reddit!
Could you explain 15 again? I picked C for it
in 15 the amount of height is z, which is what we are trying to find. Therefore, w is the age of the tree which when multiplied by 4/3 will give us the height of the tree. Hopefully, that made sense. 🙂
For 18, why is c not just 1 . I mean why is it the whole 1-k thing ?
Because each factor corresponds to the variable positions of a quadriceps equation. The x squared would correspond to the x squred, the kx would then correspond to the x- variable factor of a quadric, and then we would have the -k+1 left over, in which would finally correspond to the c variable in the quadric (the constant variable). Hope this helps.
So you mean that each number(constant) would correspond with the variable right next to it (if it has one )
The Pantry yes, this is known as manuipulating quadratics I think
Thanks!
Glad other folks were able to help you!
do you recommend princeton for sat prep?? is it good or bad
It's pretty good, I like their books.
