great. i i forgot to put that I already knew the answer thanks to wolframalpha.com i just don't know HOW to get it. In other words, can you please show work?

anonymous · Answer

x^3 + 4x^2
x^2 (x + 4)
-x - 4
-(x + 4)

Doing that will bring us to this:
x^3 + 4x^2 - x - 4 
x^2 (x + 4) - (x + 4)
 (x + 4)(x^2 - 1)
(x+4)(x+1)(x-1)

Do you understand that you start the problem with the exponents? and then make your way through PEMDAS? Remember that. Good luck
