How would I factor this?
(x3)^3+ (3x2)^3
Can someone explain this to me step by step? thanks

(1) Multiply them out.
(2) Combine terms with the same exponent of x
(3) Try to factor what is left
The last step will probably be the hardest, but you need to get there first.

dont you have a formula for the factors of two cubes?
a^3+b^3= (a+b)(a^2ab+b^2)
Here, a is x3 and b is 3x2.
