Explanation for Question 12 From the Math (No Calc) Section on the 2018 May Sat
Question 12 asks, which of the following is a solution to the equation for 2 X squared. Plus four X minus three is equal to zero. 3 So we're going to have to factor this to start. 4 I'm going to divide both sides of the equation by four. 5 So that gives me X squared plus X plus 6 negative three, over four is equal to zero. 7 Then I'm going to factor it. And that's going to give me, 8 or this is going to factor into X plus three, 9 over two X minus one. 10 Over two. That means the X is equal to negative three, 11 over two, and X is equal to one half. 12 And since negative three, over two is the only answer choice here. 13 That means that a is the crackdown.
