1. ## Factoring Homework

Hi everyone, I'm having difficulty on a problem. Please just don't answer it, break it down in steps for me. The finals are 4 days from now. Get back at me ASAP. Thanks.

3x@Sup{3}-24 or 3x^3-24 ( Three "X" to the 3rd, minus 24)

$\displaystyle \displaystyle 3x^3-24$

The common factor here is 3 so

$\displaystyle \displaystyle 3(x^3-8) =3(x^3-2^3)$

Now apply $\displaystyle \displaystyle a^3-b^3 = (a-b)(a^2+ab+b^2)$ to the expression inside the brackets.

Hey, how do you do that? The fonts and such. Anyway, it's (x-2)(x^2+2x+8) ?

Times 3, of course!

Use the LaTeX feature of this forum.
$$(x-2)(x^2+2x+8)$$ gives $\displaystyle (x-2)(x^2+2x+8)$.
