Best ResponseYou've already chosen the best response.1let the binomial be (x +a) then substitute x = a into the polynomial.... if the value of the polynomial is zero after the substitution then (x + a) is a factor. This is called the factor theorem. e.g. is (x +3) a factor of P(x) = x^2 + 5x + 6 find P(3) = (3)^2 + 5 (3) + 6 = 9  15 + 6 = 0 so (x + 3) is a factor
