Factor or can it be factored 64s^3+729x^3

• Purdue -

You are in luck with that one. Yes, it can be factored.

It is of the form a^3 + b^3, where a = 4s and b = 9y.

Recall that
a^3 + b^3 = (a + b)(a2 - ab + b2)

So one of the factors is
(4s + 9y)

See if you can figure out the other one.

Thank you I know I can from there.
