Answer 1

Is this correct? (I will put my process soon)

Answer 2

By pulling out the GCF of the 3 terms, this is what I got.
9x^2y^2(z^2+6z+9)

Answer 3

I don't see your answer

Answer 4

this is

9x^2y^2z^2 +54x^2y^2z +81x^2y^2 =

(3xyz)^2 +2*3xyz *9xy +(9xy)^2 =

=(3xyz +9xy)^2

hope this will help you

Answer 5

I'd don't think you've factored far enough. You still have common factors in your answer. Mine isn't either.
9x^2y^2(z+3)^2. I think this is the final answer
