(x+1)(x-1)=o

Solution for (x+1)(x-1)=o equation:

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

Reorder the terms:
(1 + x)(x + -1) = o

Reorder the terms:
(1 + x)(-1 + x) = o

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

Combine like terms: 1x + -1x = 0
(-1 + 0 + x2) = o
(-1 + x2) = o

Solving
-1 + x2 = o

Solving for variable 'x'.

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

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

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

Simplifying
x2 = 1 + o

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

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

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

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