Question

can someone solve this for me and tell me how they got the answer, because apparently every answer i out is incorrect (pic included)

Answer 1

B² + a²b

In this equation you have to plug into it the related values of a=2, b=-3

That is (-3)² + (2²).(-3)==> (-3)(-3) + (2)(2)(-3)

9 - 12 = - 3
