Question

Find the difference vertically.

−a^5 − (b^2 + a^2b^2) − (−a^5 − a^2b^2)

The difference is ____________.

Answer 1

$-a^{5} - ( b^{2} + a^{2} b^{2} )-( -a^{5} - a^{2} b^{2} )$
$-a^{5} + (- b^{2} - a^{2} b^{2}) + ( a^{5}+ a^{2} b^{2} )$

$-a^{5} + 0 +0$
$a^{5} + a^{2} b^{2} +0$
$0 + -a^{2} b^{2} - b^{2}$

The answer would be: $- b^{2}$
