2x+2-\left(x^{2}-1\right)\times 3=\left(x-1\right)^{2}\left(-3\right)
Variable x cannot be equal to any of the values -1,1 since division by zero is not defined. Multiply both sides of the equation by 2\left(x+1\right)\left(x-1\right)^{2}, the least common multiple of \left(x-1\right)^{2},2x-2,2x+2.
2x+2-\left(3x^{2}-3\right)=\left(x-1\right)^{2}\left(-3\right)
Use the distributive property to multiply x^{2}-1 by 3.
2x+2-3x^{2}+3=\left(x-1\right)^{2}\left(-3\right)
To find the opposite of 3x^{2}-3, find the opposite of each term.
2x+5-3x^{2}=\left(x-1\right)^{2}\left(-3\right)
Add 2 and 3 to get 5.
2x+5-3x^{2}=\left(x^{2}-2x+1\right)\left(-3\right)
Use binomial theorem \left(a-b\right)^{2}=a^{2}-2ab+b^{2} to expand \left(x-1\right)^{2}.
2x+5-3x^{2}=-3x^{2}+6x-3
Use the distributive property to multiply x^{2}-2x+1 by -3.
2x+5-3x^{2}+3x^{2}=6x-3
Add 3x^{2} to both sides.
2x+5=6x-3
Combine -3x^{2} and 3x^{2} to get 0.
2x+5-6x=-3
Subtract 6x from both sides.
-4x+5=-3
Combine 2x and -6x to get -4x.
-4x=-3-5
Subtract 5 from both sides.
-4x=-8
Subtract 5 from -3 to get -8.
x=\frac{-8}{-4}
Divide both sides by -4.
x=2
Divide -8 by -4 to get 2.
