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


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

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

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

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

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

Reorder the terms:
1 + 2x + x2 = (1 + x)(x + 1)

Reorder the terms:
1 + 2x + x2 = (1 + x)(1 + x)

Multiply (1 + x) * (1 + x)
1 + 2x + x2 = (1(1 + x) + x(1 + x))
1 + 2x + x2 = ((1 * 1 + x * 1) + x(1 + x))
1 + 2x + x2 = ((1 + 1x) + x(1 + x))
1 + 2x + x2 = (1 + 1x + (1 * x + x * x))
1 + 2x + x2 = (1 + 1x + (1x + x2))

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

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

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

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

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

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

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

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

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

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

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

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