(a^-3b) (a^2+2b)
use FOIL: multiply first, outer, inner, and last in that order
= a^4 + 2a^2b - 3a^2b- 6b^2
then group like terms if necessary and begin simplifying
= a^4 - a^b - 6b^2
that's your answer in simplest form

Expand the brackets:
(a² - 3b)(a² + 2b)
= a²(a² + 2b) - 3b(a² + 2b)
= a⁴ + 2a²b - 3a²b - 6b
= a⁴ - a²b - 6b

Use FOIL:
a^4 + 2a^2b - 3a^2b - 6b^2
and then combine the two middle terms:
a^4 - a^2b - 6b^2
That's it!
