Question

i have to factor x^3+8
im trying to figure out what multiplies to be 8 but would add to be zero? or cancel out to be zero right? (which is essentially what i need help with...)
and my answer would be written like x(x +or- ...) (x +or- ...) ?
factors of 8 are 1, 2, 4 and 8 right ? I dont think I'm missing anything... and i cant use negative numbers?

Answer 1

2 to the third is 8. 2x2x2 = 8

Answer 2

well that was stupidly simple I didnt even consider that-- thank you!

Answer 3

No problem.
