My mind is coming to a blank as to how to factor out this polynomial:

27x^3 - 8

Any help is greatly appreciated!! :D

Never mind, I think I just got it xD is this what it looks like factored out?

(x - 2/3)(x^2 + [2/3] + 12)
Answered by Emily
grrr i mean [2/3]x in the middle of the second equation

You're close.

x³-y³
=(x-y)(x²+xy+y²)

Can you take it from here?

Omg. I feel like an idiot *bangs head against wall*. Soooo it would be (3x-2)(9x²+2x+4)?
