2. alli14344

these are the answer choices: x3 – 3x2 + 9x – 27 (x2 + 9)(x2 – 9) x3 + 3x2 + 9x + 27 x3 + 3x2 – 9x – 27

3. nubeer

first u have to factorise your numerator.

4. ASLCBH

What do you think is the first step?

5. robtobey

Multiply the first answer by x+3 and simplify.

6. abb0t

$\frac{ (x^2-9)(x^2+9) }{ x+3 }$

7. abb0t

and do difference forluma on the $$x^2-9$$ to get $$(x+3)(x-3)$$
