(x+1)(x+1)=1

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

Simplifying
(x + 1)(x + 1) = 1

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

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

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

Combine like terms: 1x + 1x = 2x
(1 + 2x + x2) = 1

Add '-1' to each side of the equation.
1 + 2x + -1 + x2 = 1 + -1

Reorder the terms:
1 + -1 + 2x + x2 = 1 + -1

Combine like terms: 1 + -1 = 0
0 + 2x + x2 = 1 + -1
2x + x2 = 1 + -1

Combine like terms: 1 + -1 = 0
2x + x2 = 0

Solving
2x + x2 = 0

Subproblem 2
Set the factor '(2 + x)' equal to zero and attempt to solve:

Simplifying
2 + x = 0

Solving
2 + x = 0

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

Add '-2' to each side of the equation.
2 + -2 + x = 0 + -2

Combine like terms: 2 + -2 = 0
0 + x = 0 + -2
x = 0 + -2

Combine like terms: 0 + -2 = -2
x = -2

Simplifying
x = -2
Solution
x = {0, -2}
