Find all the zeros of the polynomial function. x^3 + 2x^2 -5x-6 f(x) a) (-3) b) (-2, 1, 3 c) (-3, -1, 2) d) -1) e) none
Flauer [41]

Answer:1,2,3

Step-by-step explanation:

F(x)=x^{3}+2x^2-5x-6=0

disintegrating 2x^2 to x^2 + x^2

x^{3}+x^2+x^2-5x-6=0

x^2\left ( x+1\right )+x^2-5x-6=0

x^2\left ( x+1\right )+x^2-6x+x-6=0

x^2\left ( x+1\right )+\left (x-6 \right )\left ( x+1\right )=0

\left ( x+1\right )\left ( x^2+x-6\right )=0

\left ( x+1\right )\left ( x^2+3x-2x-6\right )=0

\left ( x+1\right )\left ( x+3\right )\left ( x-2\right )=0
