Question

Find the product of this expression.
(m + n^2)(m^2 - mn^2 + n^4)

Answer 1

ok, you need to distribute here....
first, multiply the m in the first ( ) my each term in the second ( )
m^3 -m^2n^2 + mn^4.....

Answer 2

now multiply the n^2 in that first ( ) by each term in the back ( )...
n^2m^2 - mn^4 + n^6

Answer 3

you there?

Answer 4

now add the like terms to simplify.....
to get m^3 + n^6 (the other terms cancel out)
