x=x-1*(x*x-1*1)

Solution for x=x-1*(x*x-1*1) equation:

Simplifying
x = x + -1(x * x + -1 * 1)

Multiply x * x
x = x + -1(x2 + -1 * 1)

Multiply -1 * 1
x = x + -1(x2 + -1)

Reorder the terms:
x = x + -1(-1 + x2)
x = x + (-1 * -1 + x2 * -1)
x = x + (1 + -1x2)

Reorder the terms:
x = 1 + x + -1x2

Add '-1x' to each side of the equation.
x + -1x = 1 + x + -1x + -1x2

Combine like terms: x + -1x = 0
0 = 1 + x + -1x + -1x2

Combine like terms: x + -1x = 0
0 = 1 + 0 + -1x2
0 = 1 + -1x2

Solving
0 = 1 + -1x2

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add 'x2' to each side of the equation.
0 + x2 = 1 + -1x2 + x2
Remove the zero:
x2 = 1 + -1x2 + x2

Combine like terms: -1x2 + x2 = 0
x2 = 1 + 0
x2 = 1

Simplifying
x2 = 1

Take the square root of each side:
x = {-1, 1}
