x=1/4

Explanation:

Simplify both sides by multiplying.

The left side becomes: 3x^2-2x-1

The right side becomes: 3x^2-6x

So this becomes:

3x^2-2x-1=3x^2-6x

Subtract 3x^2 on both sides:

3x^2-2x-1-3x^2=3x^2-6x-3x^2

Simplify to get:

-2x-1=-6x

Add 6x to both sides:

-2x-1+6x=-6x+6x

Simplify:

4x-1=0

Solve for x:

4x=1

x=1/4
