Answer:
x=0 or x=0.8685170918213297 or x=−1.5351837584879966
Step-by-step explanation:
(3x3 + 2x2 - 2x - 1) = (3x - x - 1)
Add 1 to both sides
(3x3 + 2x2 - 2x) = (3x - x)
Divide both sides by 3
(x3 + 2x2 - 2x) = (x - x)
Add 1 to both sides
(3x3 + 2x2 - 2x) = (3x - x)
Divide both sides by 3
(x3 + 2x2 - 2x) = (x - x)
