Question

$$(x + 1)$$ is a factor of the polynomial :

Options

• $$x^3 + x^2 - x + 1$$

• $$x^3 + 2x^2 - x - 2$$

• $$x^3 + 4x^2 - x + 2$$

• $$x^3 + x^2 + 1$$

Answer 1

x³ + 2x² – x – 2

Explanation:

For $$x = -1$$, this polynomial evaluates to $$-1 + 2 + 1 - 2 = 0$$, so $$(x + 1)$$ is a factor.
