\left(x-2\right)x=-2x
Variable x cannot be equal to 2 since division by zero is not defined. Multiply both sides of the equation by 2\left(x-2\right), the least common multiple of 2,2-x.
x^{2}-2x=-2x
Use the distributive property to multiply x-2 by x.
x^{2}-2x+2x=0
Add 2x to both sides.
x^{2}=0
Combine -2x and 2x to get 0.
x=0 x=0
Take the square root of both sides of the equation.
x=0
The equation is now solved. Solutions are the same.

Add 2x to both sides.
x^{2}=0
Combine -2x and 2x to get 0.
x=\frac{0±\sqrt{0^{2}}}{2}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and 0 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±0}{2}
Take the square root of 0^{2}.
x=0
Divide 0 by 2.
