Select the correct answer
Kaylis [27]

Answer:

B. 1.-1,-2

Step-by-step explanation:

g(x) = x ^{3}  + 2 {x}^{2}  - x - 2

Substitute g(x)=0

0 =  {x}^{3}  + 2 {x}^{2}  - x - 2

Move the expression to the left

0 - {x}^{3}  - 2 {x}^{2}  + x + 2 = 0

Factor out -x^2 from the expression

-  {x}^{2}  \times (x + 2) + x + 2 = 0

Factor out (x+2) from the expression

(x + 2) \times ({x}^{2}  + 1) = 0

When the product of the factor equals 0, at least one factor is 0

x + 2 = 0

- {x}^{2}+ 1 > = 0

Solve for x

x =  - 2 \\ x =  - 1\\ x = 1
