Answer:

Mark it the best answer

Step-by-step explanation:

x^3+2x^2-x-2

x^2(x+2) -1(x+2)

Answer 2

Hèy Fríéñd...

Here is the Solution..

__________________

• x³ + 2x²- x - 2

• x²(x + 2) - 1(x +2)

• (x + 2)(x² - 1)

Let the polynomial equal to 0 then,

Either

(x + 2) = 0

----> ${\boxed{\bold{x = -2}}}$

Or

(x² - 1) = 0

----> x² = 1

----> ${\boxed{\bold{x = +1 or x = -1}}}$
