x+x-x(x+x)=2x-x+2

Solution for x+x-x(x+x)=2x-x+2 equation:

Simplifying
x + x + -1x(x + x) = 2x + -1x + 2

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

Remove parenthesis around (2x)
x + x + -1x * 2x = 2x + -1x + 2

Reorder the terms for easier multiplication:
x + x + -1 * 2x * x = 2x + -1x + 2

Multiply -1 * 2
x + x + -2x * x = 2x + -1x + 2

Multiply x * x
x + x + -2x2 = 2x + -1x + 2

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

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

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

Solving
2x + -2x2 = 2 + 1x

Solving for variable 'x'.

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

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

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

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

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

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
1 + -0.5x + x2 = 0

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + -0.5x + -1 + x2 = 0 + -1

Reorder the terms:
1 + -1 + -0.5x + x2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + -0.5x + x2 = 0 + -1
-0.5x + x2 = 0 + -1

Combine like terms: 0 + -1 = -1
-0.5x + x2 = -1

The x term is -0.5x.  Take half its coefficient (-0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
-0.5x + 0.0625 + x2 = -1 + 0.0625

Reorder the terms:
0.0625 + -0.5x + x2 = -1 + 0.0625

Combine like terms: -1 + 0.0625 = -0.9375
0.0625 + -0.5x + x2 = -0.9375

Factor a perfect square on the left side:
(x + -0.25)(x + -0.25) = -0.9375

Can't calculate square root of the right side.
