If you get this question wrong on the June SST, you are genuinely cooked because it is so simple as long as you know how to use a basic desmos regression.

Why it worked

The video addresses a common pain point for students preparing for the SAT (difficulty with math problems) and offers a seemingly simple, tech-based solution (Desmos regression). The urgency created by mentioning the upcoming June SAT and the promise of "200 June predictions" also likely drove engagement.

Summary

The video explains how to solve a complex SAT math problem using Desmos regression. It demonstrates rewriting the equation with variables X1 and Y1, then using a list of values for X1 to find the constants A, B, and C, and finally calculating A+B+C.

Structure

1Introduce the problem and the Desmos regression method.
2Rewrite the equation using X1 and Y1.
3Create a list of values for X1, excluding values that make the denominator zero.
4Obtain the values for constants A, B, and C.
5Calculate A+B+C.

Product placement

The video demonstrates using Desmos regression to solve a SAT math problem, implying that this method is taught or supported by the creator's service, PolyPrep.

1 This is on EVERY SAT ON THE JUNE YOU ARE BECAUSE IT IS SO SIMPLE YOU KNOW HOW BASIC DESMOS REGRESSION. EQUATION WHERE A, ARE CONSTANTS, AND WE NEED TO A+B+C WHAT WE WANNA CONSTANTS IS WE ARE GOING DESMOS REGRESSION. YOU REWRITE BUT ANYTIME YOU SEE AN X, CHANGE IT TO X1. ANYTIME YOU SEE GOING TO CHANGE IT TO Y1. AND ANYTIME YOU SIGN, CHANGE IT TO A SQUIGGLY LINE. NOW, ONCE YOU FOR X SO TRUE FOR ALL VALUES OF X. SO WE'LL SET A BRACKETTED LIST. IT DOESN'T WORK, THE BOTTOM OF A FRACTION CANNOT BE 0. DELETE THAT ONE AND THEN WE'LL GET OUR VALUES SO NOW IF A+B+C WE'LL GET

Transcript

If you get this question wrong on the June SST, you are genuinely cooked because it is so simple as long as you know how to use a basic desmos regression. We're given this equation where a B and C are constant and we need to find a plus B plus C. What we want to do whenever we have constant is we are going to write a desmos regression. This is where you rewrite the equation, but anytime you see an X, you're going to change it to X1. Anytime you see a Y, you're going to change it to Y1 and anytime you see an equal sign, you're going to change it to a squiggly line. Now, once we write out the equation, you need to make a list for X so that this is true for all values of X. So we'll set this equal to a bracketted list. We realize it when we put 5, it doesn't work and that's because the bottom of a fraction cannot be zero. And 5 - 5 is zero. So let's just delete that one. And then we'll get our values for AB and C. So now if we do A + B + C, we'll get 21.
