Explanation for Question 11 From the Math (No Calc) Section on the 2018 March Sat
Question 11 asks, which of the following expressions is equivalent to the expression above 2 for X is greater than zero. So to add and subtract like terms here, 3 I need the denominators to be the same. 4 So I'm just going to multiply this fraction on the left by two, 5 over two. And that's going to give us four over six X squared, 6 minus one, over six X squared, 7 which is just equal to three over six X squared. 8 And then I can simplify that divide the top and the bottom by three. 9 And I get one to the third X squared or X squared 10 over three. And that answer is answer choice C.
