Question

if x-a is a factor of the polynomial 7x^3+12x^2-26x+3. what is a possible value of a?

Answer 1

(x - a) is a factor if the polynomial is divided exactly by (x - a)

Answer 2

A)-3 B)-2 C)2 D)3

Answer 3

use the remainder theorem

Answer 4

it states that the remainder of a polynomial f(x) divided by a linear divisor (x - a) is equal to f(a), because (x - a) is a factor then f(a) = 0
