-12x^3+(x+2)(2x-1)=(-2x^2+1)(6x-1)+9

Solution

- 12 x^{3} + (x + 2) \cdot (2 x - 1) = (- 2 x^{2} + 1) \cdot (6 x - 1) + 9

Solution

x = - \frac{10}{3}

Solution steps

- 12 x^{3} + (x + 2) (2 x - 1) = (- 2 x^{2} + 1) (6 x - 1) + 9

Expand

(x + 2) (2 x - 1) : 2 x^{2} + 3 x - 2

- 12 x^{3} + 2 x^{2} + 3 x - 2 = (- 2 x^{2} + 1) (6 x - 1) + 9

Expand

(- 2 x^{2} + 1) (6 x - 1) + 9 : - 12 x^{3} + 2 x^{2} + 6 x + 8

- 12 x^{3} + 2 x^{2} + 3 x - 2 = - 12 x^{3} + 2 x^{2} + 6 x + 8

Move

to the right side

- 12 x^{3} + 2 x^{2} + 3 x = - 12 x^{3} + 2 x^{2} + 6 x + 10

Subtract

- 12 x^{3} + 2 x^{2} + 6 x

from both sides

- 12 x^{3} + 2 x^{2} + 3 x - (- 12 x^{3} + 2 x^{2} + 6 x) = - 12 x^{3} + 2 x^{2} + 6 x + 10 - (- 12 x^{3} + 2 x^{2} + 6 x)

Simplify

- 3 x = 10

Divide both sides by

- 3

x = - \frac{10}{3}
