Question

Heres a simple x^3 one - i just forgot how to do them. f(x)=x^3 - 2x^2 - 13x - 10 as (x-a) (x-b) (x-c) [Simply the 3 factors for this equation]. (x+2) is one of them.

Answer 1

Its a Factor Theorem one i think

Answer 2

where f(a) is a factor of (x-a)

Answer 3

is there 5 and 1?

Answer 4

as 2x5x-1

Answer 5

or -2 x 5 x 1
or -2 x -5 x -1

Answer 6

i think ill check them out

Answer 7

divide f(x) by x+2
