NOTE: If the lines around the equation are absolute value lines, the answer will be the positive version of the answer given. The lines looked like you were just clarifying where the equation was in the sentence, but I could be wrong.
First, plug all the numbers in. So it would be (2(3)(-2)^{2} ). Then you would apply the exponant to the -2. So that would be (2(3)(4)). And that equals 24.
