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
