Answer 2

can you please show work with this one

Answer 3

I'll add the first two terms into parenthesis.
(z + 3)

Using the formula (a+b)*(a^2+ab+b^2) I can plug in my second set of parenthesis
I know it's a sum of two cubes. So I know my terms will be descending .
(z + 3)(z^2 + 3z + 9)

Answer 4

so thats the answer?

Answer 5

Yes

Answer 6

it told me its wrong idk

Answer 7

There is a slight error here. The first sign in the trinomial is wrong.
z^3 + 27 = (z + 3)(z^2 - 3z + 9)
