I was so frustrated with magoosh and manhattan 5 lb combo. You've just made it crystal clear. Take a bow man!

[@dhananjayshelar8490]

Thanks for the video!
Shortcut: If factorization is tough for someone in parabola, y= ax^2 + bx + c
1. X-intercept is '-b/2a' from the equation.
2. Substitute X-intercept in the equation for 'x' and find 'y'.
3. (X-int, Y-int) is your vertex

your contents are so so so wonderful!! It's helped me so much with the GRE and made me feel much more confident. THANK YOU and wishing you all the best!

Great video and easy to follow. Could you do a video on overlapping set(Venn diagram)

[@valerias.9621]

Philip, thank you SO very much! I have watched and noted already 42 different themes (this one is 43th) thanks to your videos, which is starting to make a solid book :) I am really grateful, as I find all of your content extremely of use for my gmat preparation.

[@TheTestedTutor]

Thank you! That's a lot...

[@valerias.9621]

@@TheTestedTutor it may seem a lot, but it was absolutely worth investing time for me! It took me about 4 days and there are a couple of videos left. Actually, I have gathered all the possibles themes from the gmat quant into a list and then next to all of them I put the number of the theme from your video. So that’s why I can certainly say that you have made e.g 3 probability videos or 4 videos on remainders and divisibility, etc. The only themes that are not covered fully so far are: percentages, mode, range, odd and evens, decimals, quadrilaterals. But I won’t dare asking you to make videos of them, because it the amount of the themes you HAVE covered is enormous. I am a huge fan!

[@tusharkumar7963]

Hey! Can you please share your notes with me? It'll be really helpful. Let me know if you are comfortable with it😀

You could use differentiation to determine the minima/maxima followed by double differential to determine whether it's maxima or minima

Thanks Lasita

@tested tutor, why don’t you reply? Please make our confusion clear.

[@infxtv2646]

Finding the average makes so much sense - I see it visually as figuring out the middle point on the graph between the x-intercepts. Is this a correct way to think of it? Great vid to sip my morning coffee to ☕😌 thanks Philip! -Hillary

[@TheTestedTutor]

Yes, exactly. So glad it makes sense. :)

[@soumendash3911]

ya thanks for this comment initially i skipped that but second time when I paid attention I got that nice explanation sir

[@sepiferdos2029]

Thank you for this video! It was really helpful to understand parabolas. Do you still tutor individually by chance? I'm taking my GRE at the end of October and aiming to increase my score to around 165 at least and I'm finding this difficult. Thanks!

Yes I do! But fully booked at the moment

Also Philip. Please do a video on deck of cards and dice related problems. Those that concerns unbiased and biased conditions. I always go wrong in them. :(

hii Philip i just wanted to know in the y-coordinate the answer was coming to -20.25 and you wrote 20.25 I am a bit confused about that could you pls clear that up?

[@SWASTIKB306]

Thanks Philip for that . Owe your videos a lot.

[@TheTestedTutor]

So nice of you

[@kaveriponkshe5652]

In the last example isn't y vertex (-20.25)?

[@user-ce2il5ct5i]

this trick a gangsta until a parabola without x-intercept comes!

[@user-ce2il5ct5i]

you should then use the formula.

[@HarshaAchanta-qm8oo]

Hi , i solved the equation as it is i.e y=-x2+x+20 and i got the below results . x,y of vertex is (-0.5, 19.75) how is that possible ? even if we change sign the answers should be same right ? pls suggest.

[@shritisingh1301]

In unhappy parabola -how did you get y= 20.25. Shouldn’t it be -20.25 ?

[@mauriciolimon3857]

having the same question

[@danielgiraldo3692]

No, look at the graph in the video: you have a positive Y point and still all the parabola going downwards from that point. You can have also a unhappy parabola from a negative Y point, but that’s not the case presented in the formula

[@dhamotharann3806]

Awesomen

[@TheTestedTutor]

Thanks 🤗

[@ashishsinha9035]

Is Parabola relevant for GMAT?

[@gangavarapuanandkumar5524]

its suppose to be -20.25 right?

don't dictate it, solve it on the screen we have to spend many more minute's to understand the saying
