(x)(x+1)+11=(x)(x+1)

Solution for (x)(x+1)+11=(x)(x+1) equation:

Simplifying
(x)(x + 1) + 11 = (x)(x + 1)

Reorder the terms:
x(1 + x) + 11 = (x)(x + 1)
(1 * x + x * x) + 11 = (x)(x + 1)
(1x + x2) + 11 = (x)(x + 1)

Reorder the terms:
11 + 1x + x2 = (x)(x + 1)

Reorder the terms:
11 + 1x + x2 = x(1 + x)
11 + 1x + x2 = (1 * x + x * x)
11 + 1x + x2 = (1x + x2)

Add '-1x' to each side of the equation.
11 + 1x + -1x + x2 = 1x + -1x + x2

Combine like terms: 1x + -1x = 0
11 + 0 + x2 = 1x + -1x + x2
11 + x2 = 1x + -1x + x2

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

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

Combine like terms: x2 + -1x2 = 0
11 + 0 = x2 + -1x2
11 = x2 + -1x2

Combine like terms: x2 + -1x2 = 0
11 = 0

Solving
11 = 0
