evaluate the following expression if a= -2, h=5 and w= -8

aw^2(w is squared)-hw

I did (-2)(-8)^2-(5)(-8)

(-2)64-(5)(-8)

-128-(5)(-8)

-128-(-40)

-128=40= -88

I believe this is correct but I want to make sure.

Thank you for your help

correct

however, your line

-128=40= -88 makes no sense,

It is probably a typo, since the + and = are only a "shift" away from each other.
