Solution for x^2=(x+1)(x+1) equation:


Simplifying
x2 = (x + 1)(x + 1)

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

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

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

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

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

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

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

Solving
0 = 1 + 2x

Solving for variable 'x'.

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

Add '-2x' to each side of the equation.
0 + -2x = 1 + 2x + -2x
Remove the zero:
-2x = 1 + 2x + -2x

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

Divide each side by '-2'.
x = -0.5

Simplifying
x = -0.5
