Which of the following is a root of the polynomial shown below? f(x) = x2 + 2x2 - x-2
O A. 1
OB. 3
O c. O
O D. 2

We conclude that option A is true as x = 1 is the root of the polynomial.

Step-by-step explanation:

Given the polynomial

Let us determine the root of the polynomial shown below.

switch sides

as

so the equation becomes

Using the zero factor principle

solving

and

The possible roots of the polynomial will be:

Therefore, from the mentioned options, we conclude that option A is true as x = 1 is the root of the polynomial.
