Gmat real question but answer is wrong

If AB = 40, what is the value of AB(A + 2B)?

(1) A – B = -18.

(2) A( AB ) = 80.

As ans given “its B”

how A also satisfies the ans so it must be D

A-B = -18 and AB =40

so square(A+B )= square(A-B)+4AB

=> A+B = 22 not -22 as either A and B both will b negative or both will be positive  since AB =40 and A-B = -18 show B >A so when B-A =18 , B is positive and A is positve so A+ B is positive.

so A+ B =22 and A- B =-18 , implies B = 20 and A=2

so AB (A+ 2B) =1680 same as option b gives.
