2x+6+2xx=\left(x-1\right)\left(2x+9\right)
Variable x cannot be equal to any of the values -3,0,1 since division by zero is not defined. Multiply both sides of the equation by 2x\left(x-1\right)\left(x+3\right), the least common multiple of x^{2}-x,x^{2}+2x-3,2x^{2}+6x.
2x+6+2x^{2}=\left(x-1\right)\left(2x+9\right)
Multiply x and x to get x^{2}.
2x+6+2x^{2}=2x^{2}+7x-9
Use the distributive property to multiply x-1 by 2x+9 and combine like terms.
2x+6+2x^{2}-2x^{2}=7x-9
Subtract 2x^{2} from both sides.
2x+6=7x-9
Combine 2x^{2} and -2x^{2} to get 0.
2x+6-7x=-9
Subtract 7x from both sides.
-5x+6=-9
Combine 2x and -7x to get -5x.
-5x=-9-6
Subtract 6 from both sides.
-5x=-15
Subtract 6 from -9 to get -15.
x=\frac{-15}{-5}
Divide both sides by -5.
x=3
Divide -15 by -5 to get 3.
