Explanation for Question 7 From the Math (No Calc) Section on the 2018 March Sat
Question seven asks what is the solution set to the equation above? 2 So to solve this problem, I'm going to set both of these, 3 uh, parts of the parentheses equal to zero. 4 So first two X minus one is equal to zero. 5 In this case, X is equal to one half. 6 So we know that that's one of the solutions to this equation. 7 And then when X plus two is set equal to zero X is equal 8 to negative two. So we know that X is equal to one half, 9 and X is equal to negative two. 10 And from that we know that the correct answer is answer choice. 11 Okay.
