x\left(x-2\right)\left(-2\right)+2\left(x+2\right)\left(x-2\right)^{2}=2\left(x+2\right)x+2x\left(x-2\right)^{2}
Variable x cannot be equal to any of the values -2,0,2 since division by zero is not defined. Multiply both sides of the equation by 2x\left(x+2\right)\left(x-2\right)^{2}, the least common multiple of 2x^{2}-8,x,\left(x-2\right)^{2},x+2.
\left(x^{2}-2x\right)\left(-2\right)+2\left(x+2\right)\left(x-2\right)^{2}=2\left(x+2\right)x+2x\left(x-2\right)^{2}
Use the distributive property to multiply x by x-2.
-2x^{2}+4x+2\left(x+2\right)\left(x-2\right)^{2}=2\left(x+2\right)x+2x\left(x-2\right)^{2}
Use the distributive property to multiply x^{2}-2x by -2.
-2x^{2}+4x+2\left(x+2\right)\left(x^{2}-4x+4\right)=2\left(x+2\right)x+2x\left(x-2\right)^{2}
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(x-2\right)^{2}.
-2x^{2}+4x+\left(2x+4\right)\left(x^{2}-4x+4\right)=2\left(x+2\right)x+2x\left(x-2\right)^{2}
Use the distributive property to multiply 2 by x+2.
-2x^{2}+4x+2x^{3}-4x^{2}-8x+16=2\left(x+2\right)x+2x\left(x-2\right)^{2}
Use the distributive property to multiply 2x+4 by x^{2}-4x+4 and combine like terms.
-6x^{2}+4x+2x^{3}-8x+16=2\left(x+2\right)x+2x\left(x-2\right)^{2}
Combine -2x^{2} and -4x^{2} to get -6x^{2}.
-6x^{2}-4x+2x^{3}+16=2\left(x+2\right)x+2x\left(x-2\right)^{2}
Combine 4x and -8x to get -4x.
-6x^{2}-4x+2x^{3}+16=\left(2x+4\right)x+2x\left(x-2\right)^{2}
Use the distributive property to multiply 2 by x+2.
-6x^{2}-4x+2x^{3}+16=2x^{2}+4x+2x\left(x-2\right)^{2}
Use the distributive property to multiply 2x+4 by x.
-6x^{2}-4x+2x^{3}+16=2x^{2}+4x+2x\left(x^{2}-4x+4\right)
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(x-2\right)^{2}.
-6x^{2}-4x+2x^{3}+16=2x^{2}+4x+2x^{3}-8x^{2}+8x
Use the distributive property to multiply 2x by x^{2}-4x+4.
-6x^{2}-4x+2x^{3}+16=-6x^{2}+4x+2x^{3}+8x
Combine 2x^{2} and -8x^{2} to get -6x^{2}.
-6x^{2}-4x+2x^{3}+16=-6x^{2}+12x+2x^{3}
Combine 4x and 8x to get 12x.
-6x^{2}-4x+2x^{3}+16+6x^{2}=12x+2x^{3}
Add 6x^{2} to both sides.
-4x+2x^{3}+16=12x+2x^{3}
Combine -6x^{2} and 6x^{2} to get 0.
-4x+2x^{3}+16-12x=2x^{3}
Subtract 12x from both sides.
-16x+2x^{3}+16=2x^{3}
Combine -4x and -12x to get -16x.
-16x+2x^{3}+16-2x^{3}=0
Subtract 2x^{3} from both sides.
-16x+16=0
Combine 2x^{3} and -2x^{3} to get 0.
-16x=-16
Subtract 16 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-16}{-16}
Divide both sides by -16.
x=1
Divide -16 by -16 to get 1.
