Let's start by moving all like terms to their own sides:
-18 = -3x + 6
3x = 6 + 18
3x = 24
x = 8
-v6,-23,2,2.5
Correct to ascending order
-9x^3-72x^2+36=3x^3+x^2-3x+8 Add 9x^3 to both sides.
-72x^2 + 36 = 3x^3 + 9x^3 + x^2 - 3x + 8 Add 72x^2 to both sides
36 = 12x^3 + 73x^2 - 3x + 8 Subtract 36 from both sides.
0 = 12x^3 + 73x^2 - 3x - 28
It does factor, but it is not very nice.
(x + 6.06)(x - 6.09)(x + 0.632)

Answer:
x = 6
Step-by-step explanation:
To find x we set up an equation as so:

Then we solve by multiplying 4.5 by 8 and 6 by x
Solve for x
x = 6
To check our answer when we substitute x or 6 we divide to make sure both sides equal the same number
when divided both equals 0.75
