2x^{2}-\left(3x-6ax\right)-2=0
Use the distributive property to multiply 3-6a by x.
2x^{2}-3x+6ax-2=0
To find the opposite of 3x-6ax, find the opposite of each term.
-3x+6ax-2=-2x^{2}
Subtract 2x^{2} from both sides. Anything subtracted from zero gives its negation.
6ax-2=-2x^{2}+3x
Add 3x to both sides.
6ax=-2x^{2}+3x+2
Add 2 to both sides.
6xa=2+3x-2x^{2}
The equation is in standard form.
\frac{6xa}{6x}=\frac{\left(2-x\right)\left(2x+1\right)}{6x}
Divide both sides by 6x.
a=\frac{\left(2-x\right)\left(2x+1\right)}{6x}
Dividing by 6x undoes the multiplication by 6x.
a=-\frac{x}{3}+\frac{1}{2}+\frac{1}{3x}
Divide \left(1+2x\right)\left(2-x\right) by 6x.
