plz

Answer 3

To 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) = (x-2) (x-1) (x+2)

x = 2
x = 1
x = -2

Answer 4

How did you get to g(x) = (x-2) (x-1) (x+2) please i don't understand how you got there @izuru

Answer 5

Factor 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)

OK thank you!
