Question

(h – 3) (h^2 + 2h – 8)

Answer 1

`h^3-h^2-14h+24`

Explanation:

First step I did was expand the equation! After that, you simply simplify the remaining terms!

`(h - 3) (h^2 + 2h - 8)\\hh^2+h\cdot \:2h+h\left(-8\right)+\left(-3\right)h^2+\left(-3\right)\cdot \:2h+\left(-3\right)\left(-8\right)`

I understand how this step might look a bit confusing, but all I did was distribute here!

`h^2h+2hh-8h-3h^2-3\cdot \:2h+3\cdot \:8\\h^3+2h^2-8h-3h^2-6h+24\\h^3+2h^2-3h^2-8h-6h+24\\h^3-h^2-8h-6h+24`

Our grand total is...

`h^3-h^2-14h+24!`

Answer 2

h^3 - h^2 - 13h + 24
