# Factored Form

#### Glitch

Hey guys,

I'm having trouble factorising this following:

8x^6 + 64

I've done the following:

8(x^6 + 8)

I'm not sure how to factorise this further. Please provide detailed steps so I can understand. Thank you.

Use the sum of two cubes rule

$$\displaystyle a^3 + b^3 = (a + b)(a^2 - ab + b^2)$$.

In your case, $$\displaystyle 8(x^6 + 8) = 8[(x^2)^3 + 3^3]$$.
