Best ResponseYou've already chosen the best response.0To find the zero of the polynomial function, you need to set it equal to 0 first. g(x) = x^3 − x^2 − 4x + 4 It has a total of three zeros. g(x) = (x2) (x1) (x+2) x = 2 x = 1 x = 2

Best ResponseYou've already chosen the best response.0How did you get to g(x) = (x2) (x1) (x+2) please i don't understand how you got there @izuru

Best ResponseYou've already chosen the best response.0Factor out common terms in the first two terms, then in the last two terms. x^2(x−1)−4(x−1) Factor out the common term x−1 (x−1)(x^2−4) x^2−4 fits the form a^2−b^2 Rewrite it as a = x and b = 2 (x−1)(x^2−22) Use Difference of Squares: a^2−b^2 = (a+b) (a−b) (x−1)(x+2)(x−2)
