\left(x-6\right)\left(x-2\right)+6\left(x+2\right)\left(x-2\right)=\left(x-6\right)\left(x+2\right)
Variable x cannot be equal to any of the values -2,6 since division by zero is not defined. Multiply both sides of the equation by \left(x-6\right)\left(x+2\right), the least common multiple of x+2,x-6.
x^{2}-8x+12+6\left(x+2\right)\left(x-2\right)=\left(x-6\right)\left(x+2\right)
Use the distributive property to multiply x-6 by x-2 and combine like terms.
x^{2}-8x+12+\left(6x+12\right)\left(x-2\right)=\left(x-6\right)\left(x+2\right)
Use the distributive property to multiply 6 by x+2.
x^{2}-8x+12+6x^{2}-24=\left(x-6\right)\left(x+2\right)

Combine -8x and 4x to get -4x.
6x^{2}-4x-12+12=0
Add 12 to both sides.
6x^{2}-4x=0
Add -12 and 12 to get 0.
x=\frac{-\left(-4\right)±\sqrt{\left(-4\right)^{2}}}{2\times 6}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 6 for a, -4 for b, and 0 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{-\left(-4\right)±4}{2\times 6}
Take the square root of \left(-4\right)^{2}.
x=\frac{4±4}{2\times 6}
The opposite of -4 is 4.
x=\frac{4±4}{12}
Multiply 2 times 6.
x=\frac{8}{12}
Now solve the equation x=\frac{4±4}{12} when ± is plus. Add 4 to 4.
x=\frac{2}{3}
Reduce the fraction \frac{8}{12} to lowest terms by extracting and canceling out 4.
x=\frac{0}{12}
Now solve the equation x=\frac{4±4}{12} when ± is minus. Subtract 4 from 4.
x=0
Divide 0 by 12.
x=\frac{2}{3} x=0
The equation is now solved.
\left(x-6\right)\left(x-2\right)+6\left(x+2\right)\left(x-2\right)=\left(x-6\right)\left(x+2\right)
Variable x cannot be equal to any of the values -2,6 since division by zero is not defined. Multiply both sides of the equation by \left(x-6\right)\left(x+2\right), the least common multiple of x+2,x-6.

\frac{6x^{2}-4x}{6}=\frac{0}{6}
Divide both sides by 6.
x^{2}+\left(-\frac{4}{6}\right)x=\frac{0}{6}
Dividing by 6 undoes the multiplication by 6.
x^{2}-\frac{2}{3}x=\frac{0}{6}
Reduce the fraction \frac{-4}{6} to lowest terms by extracting and canceling out 2.
x^{2}-\frac{2}{3}x=0
Divide 0 by 6.
x^{2}-\frac{2}{3}x+\left(-\frac{1}{3}\right)^{2}=\left(-\frac{1}{3}\right)^{2}
Divide -\frac{2}{3}, the coefficient of the x term, by 2 to get -\frac{1}{3}. Then add the square of -\frac{1}{3} to both sides of the equation. This step makes the left hand side of the equation a perfect square.
x^{2}-\frac{2}{3}x+\frac{1}{9}=\frac{1}{9}
Square -\frac{1}{3} by squaring both the numerator and the denominator of the fraction.
\left(x-\frac{1}{3}\right)^{2}=\frac{1}{9}
Factor x^{2}-\frac{2}{3}x+\frac{1}{9}. In general, when x^{2}+bx+c is a perfect square, it can always be factored as \left(x+\frac{b}{2}\right)^{2}.
\sqrt{\left(x-\frac{1}{3}\right)^{2}}=\sqrt{\frac{1}{9}}
Take the square root of both sides of the equation.
x-\frac{1}{3}=\frac{1}{3} x-\frac{1}{3}=-\frac{1}{3}
Simplify.
x=\frac{2}{3} x=0
Add \frac{1}{3} to both sides of the equation.
