Question

How do you find the product `(2m+3)(2m-3)(m+4)`?

Answer 1

`4m^3-16m^2-9m-36`

Explanation:

`(2m+3)(2m-3)` is a difference of squares so you can either F.O.I.L. or use difference of squares`=(4m^2-9)`

next multiply by the remaining factor `(m+4)`

`(4m^2-9)(m+4)` foiled equals `4m^3-16m^2-9m-36`
