I got some homework problems that require me to multiply factored polynomials and write them in standard form. I thought it was easy enough until I saw that some were cubed. How do I multiply these?
ex: (2x + 5)^3
So far I figured that I would have an 8x^3 and that I can set it up like this:
(2x + 5)*(2x + 5)*(2x + 5)
But I'm lost after that. I dont want to just be told the answer, but I would appreciate it if someone could explain to me how to do a problem like this.
