Question

I need help plz, only if you now the answer

Answer 1

Answer:

{-2, 1, 2}

Step-by-step explanation:

F(x) = x³ - x² - 4x + 4 is factorable as follows:

F(x) = x²(x - 1) - 4(x - 1).  (x - 1) is a common factor.  Factor it out:

F(x) = (x - 1)(x² - 4)

x² - 4 can be factored further:

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

The possible roots of F(x) are {-2, 1, 2}.
