1=\left(x-1\right)\left(-x-1\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 \left(x-1\right)\left(-x-1\right).
1=-x^{2}+1
Use the distributive property to multiply x-1 by -x-1 and combine like terms.
-x^{2}+1=1
Swap sides so that all variable terms are on the left hand side.
-x^{2}=1-1
Subtract 1 from both sides.
-x^{2}=0
Subtract 1 from 1 to get 0.
x^{2}=0
Divide both sides by -1. Zero divided by any non-zero number gives zero.
x=0 x=0
Take the square root of both sides of the equation.
x=0
The equation is now solved. Solutions are the same.

x=\frac{0±\sqrt{0^{2}}}{2}
This equation is in standard form: ax^{2}+bx+c=0. Substitute 1 for a, 0 for b, and 0 for c in the quadratic formula, \frac{-b±\sqrt{b^{2}-4ac}}{2a}.
x=\frac{0±0}{2}
Take the square root of 0^{2}.
x=0
Divide 0 by 2.
