Question

Factor.

x^3-729

Answer 1

a^3-b^3=(a-b)(a^2+ab+b^2)
x^3-729=x^3-9^3
Does that help?

Answer 2

yeah that makes sense because 9^3 = 729.

Answer 3

Use this to factor it
a^3-b^3=(a-b)(a^2+ab+b^2)
Here a=x and b=9

Answer 4

So the end equation would be (x^3-9^3)

Answer 5

nope.
a^3-b^3=(a-b)(a^2+ab+b^2)
Plug in a=x and b=9 in (a-b)(a^2+ab+b^2)
