Answer:

x=−0.825789

Step-by-step explanation:

x=(−6x3−4x−6)/x

Step 1: Multiply both sides by x.

x2=−6x3−4x−6

x2−(−6x3−4x−6)=−6x3−4x−6−(−6x3−4x−6)(Subtract -6x^3-4x-6 from both sides)

6x3+x2+4x+6=0

(Use cubic formula)

x=−0.825789

Answer:

- 3

Step-by-step explanation:

Substitute x = - 6 into the expression

[tex]\frac{(-6)^2-6}{-6-4}[/tex]

= [tex]\frac{36-6}{-10}[/tex] = [tex]\frac{30}{-10}[/tex] = - 3
