Given f(x) = x3 – 2x2 – x + 2, the roots of f(x) are

The zeros of the given polynomial function are 1, -1 and 2

Given the polynomial function

First, we need to assume a value of x to check if it will give us zero after substituting:

Assuming x = 1

Since f(1) =0, hence x - 1 is a factor

Dividing x - 1 by the given polynomial function, we will have:

Equating the result to zero

x + 1 = 0 and x - 2 = 0

x = -1 and 2

Hence the zeros of the given polynomial function are 1, -1 and 2
