Question

A factor of factors of 6x3 + 6 is x + 1?

Answer 1

use the factor theorem

if\[ P(x) = 6x^3 + 6 \]

then find P(-1)

if P(-1) = 0 then x + 1 is a factor

Answer 2

I like that factor theorem. Or you could divide using long division or synthetic division to see if x+1 divides into 6x^3+6 evenly (no remainder.) If so, it's a factor.

Answer 3

@campbell_st took P(-1) becoz he put this value at the place of x then P(-1)=0. so x=-1 =>x+1 is a factor.

Answer 4

got it?
