3x^{2}-3x+1=\left(x-1\right)\left(x+1\right)\times 3+\left(x-1\right)\times 2-\left(x+1\right)\times 3
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 \left(x-1\right)\left(x+1\right), the least common multiple of x^{2}-1,x+1,x-1.
3x^{2}-3x+1=\left(x^{2}-1\right)\times 3+\left(x-1\right)\times 2-\left(x+1\right)\times 3
Use the distributive property to multiply x-1 by x+1 and combine like terms.
3x^{2}-3x+1=3x^{2}-3+\left(x-1\right)\times 2-\left(x+1\right)\times 3
Use the distributive property to multiply x^{2}-1 by 3.
3x^{2}-3x+1=3x^{2}-3+2x-2-\left(x+1\right)\times 3
Use the distributive property to multiply x-1 by 2.
3x^{2}-3x+1=3x^{2}-5+2x-\left(x+1\right)\times 3
Subtract 2 from -3 to get -5.
3x^{2}-3x+1=3x^{2}-5+2x-\left(3x+3\right)
Use the distributive property to multiply x+1 by 3.
3x^{2}-3x+1=3x^{2}-5+2x-3x-3
To find the opposite of 3x+3, find the opposite of each term.
3x^{2}-3x+1=3x^{2}-5-x-3
Combine 2x and -3x to get -x.
3x^{2}-3x+1=3x^{2}-8-x
Subtract 3 from -5 to get -8.
3x^{2}-3x+1-3x^{2}=-8-x
Subtract 3x^{2} from both sides.
-3x+1=-8-x
Combine 3x^{2} and -3x^{2} to get 0.
-3x+1+x=-8
Add x to both sides.
-2x+1=-8
Combine -3x and x to get -2x.
-2x=-8-1
Subtract 1 from both sides.
-2x=-9
Subtract 1 from -8 to get -9.
x=\frac{-9}{-2}
Divide both sides by -2.
x=\frac{9}{2}
Fraction \frac{-9}{-2} can be simplified to \frac{9}{2} by removing the negative sign from both the numerator and the denominator.
