This question is made up. It is very similar to a problem I saw on the official GMAT, with the main kicker being the -5^2 ... I don't have the OA and I was stumped by this question on the test

GMATBusters · Answer

x = (-5^2-5) +(2*3(-5))
= (-25-5) +(-30)
= -30-30
= -60
Answer D

Trap   (-5)^2 = (-5)*(-5) = 25, but -5^2 = -(5*5)= -25

Abhishek009 · Answer

x = (-5^2 - 5) + (2*3*(-5))

Or,  x = (a^2 + a) + (2*3*(a))  If u take a = -5 Here it is -(a)^2+a + 2*3*a

Or,  x = (a^2 + a+ 6a)

Or,  x = (a^2 +7a)

Or,  x = a(a + 7)

Or,  x = -5(-5 + 7)

Or,  x = -10 , Answer must be (A)
