x\left(2x+1\right)=\left(x-2\right)\left(2x+6\right)
Variable x cannot be equal to any of the values 0,2 since division by zero is not defined. Multiply both sides of the equation by x\left(x-2\right), the least common multiple of x-2,x.
2x^{2}+x=\left(x-2\right)\left(2x+6\right)
Use the distributive property to multiply x by 2x+1.
2x^{2}+x=2x^{2}+2x-12
Use the distributive property to multiply x-2 by 2x+6 and combine like terms.
2x^{2}+x-2x^{2}=2x-12
Subtract 2x^{2} from both sides.
x=2x-12
Combine 2x^{2} and -2x^{2} to get 0.
x-2x=-12
Subtract 2x from both sides.
-x=-12
Combine x and -2x to get -x.
x=12
Multiply both sides by -1.
