[November SAT Math] Every SAT Parabola Question Types - Tips/Tricks to Always Get Them Right

👇👇👇 [Expand for the summary] 👇👇👇

What's up HACKERS!

Welcome to today’s video on Parabola/quadratics. We are going to go over the 3 types of questions you must know to answer all the parabola/quadratics questions on the SAT.

Type 1: Definition of the root / Finding roots
What you need to know - Recognize that when the equation is set equal to zero, the solution is referring to the root/x-intercepts. (When y=0, it’s referring to the x-intercepts)
How to recognize - Equation with a highest power to the 2.
What to be aware of - There are two ways to find the roots - factoring & quadratic formula. Always use factoring and only use the quadratic formula when the answer choices have radical and/or +/- in it.

Type 2: Sum of the roots
What you need to know - the equations for sum (-b/a) and product (c/a)
How to recognize - The question will directly ask you to find the sum / product of the solution.
What to be aware of - When asked to find a sum/product DO NOT FIND EACH SOLUTION INDIVIDUALLY. You will eventually get the answer, but It’s a huge waste of time

Type 3: Number of roots
What you need to know - You can find the # of roots a parabola has via discriminants (b^2-4ac).
How to recognize - The question will either say that the parabola has “no solution” “one solution” or “two solutions.” Remember, you can only use discriminants for a PARABOLA. Similar question will show up for two lines, but you can’t use discriminant for lines (it doesn’t have a,b,c to plug into the discriminant formula.
What to be aware of:
1. Don’t use it for the line.
2. There are two types of discriminant questions the SAT asks for. Finding the # of roots is the first type, the second type is finding the number of intersection between line and a parabola. The second type is covered in the lecture link above.

Everything on this video is still tested on the Digital SAT. If anything new is added, will create a new video.

The "t" I plugged @ 11:51 should've been "-t" (because the "c" value is -t) ===> So the sign for the final answer would be flipped and the correct answer would be A

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 spent hundreds of dollars on sat prepping and your free YouTube video helped me more than any of my tutors 😭

[black_rose_bv]

[AR-fszz]

Thank you so much for this video. I got a 780 on the math section and your channel was a big help when I was studying.

[mariegregory]

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.

[valeria]

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?

[austinpruitt]

You are such an excellent communicator. Please keep making videos on YouTube

[omoyemehsabo-simeon]

[braxtonwalker]

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)<0 And answer -3.

[adeboyejoayoyemi]

Thank you so much for these videos. They are super helpful. Please can you make a short video on factoring 🙏?

[_maryam]

I am so lucky cuz I found your channel before my test day ... Thanks a lot 😍

[TheRizwanShaik]

I love your videos man!! thank you! Can you please do a videos on "isolating complex quantaties" ?

[ianollmann]

I feel like 3. Number of roots would have been more easily solved by simplifying 16-8t<0 to 2<t. Then picking the right answer is quick and easy.

[khope]

Thank you John🤝🏿, currently reviewing and revising 1 week before my Test date😅. Coming in clutch fr

[nameera.f.s.]

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.

Insanely helpful video my SAT is in December tysm
