Respuesta :

Given the polynomial functions:

[tex]F(x)=x^3+x^2-6x[/tex]

We can express this polynomial in factored form:

[tex]F(x)=x(x^2+x-6)[/tex]

But:

[tex]x^2+x-6=(x+3)(x-2)[/tex]

Then:

[tex]F(x)=x(x+3)(x-2)[/tex]

Finally, to find the zeros of the polynomial, we solve the equation:

[tex]x(x+3)(x-2)=0[/tex]

This cubic equation turns into three linear equations:

[tex]\begin{gathered} x=0 \\ x+3=0\Rightarrow x=-3 \\ x-2=0\Rightarrow x=2 \end{gathered}[/tex]

Answer:

[tex]D.\text{ }x=-3,x=0,x=2[/tex]
