Solving for variable 'x'.

Begin completing the square.

Move the constant term to the right:

Add '112' to each side of the equation.
-112 + x + 112 + x2 = 0 + 112

Reorder the terms:
-112 + 112 + x + x2 = 0 + 112

Combine like terms: -112 + 112 = 0
0 + x + x2 = 0 + 112
x + x2 = 0 + 112

Combine like terms: 0 + 112 = 112
x + x2 = 112

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

Add '0.25' to each side of the equation.
x + 0.25 + x2 = 112 + 0.25

Reorder the terms:
0.25 + x + x2 = 112 + 0.25

Combine like terms: 112 + 0.25 = 112.25
0.25 + x + x2 = 112.25

Factor a perfect square on the left side:
(x + 0.5)(x + 0.5) = 112.25

Calculate the square root of the right side: 10.59481005

Solving for variable 'x'.

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

Add '-0.5' to each side of the equation.
0.5 + -0.5 + x = 10.59481005 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + x = 10.59481005 + -0.5
x = 10.59481005 + -0.5

Combine like terms: 10.59481005 + -0.5 = 10.09481005
x = 10.09481005

Simplifying
x = 10.09481005

Subproblem 2
x + 0.5 = -10.59481005

Simplifying
x + 0.5 = -10.59481005

Reorder the terms:
0.5 + x = -10.59481005

Solving
0.5 + x = -10.59481005

Solving for variable 'x'.

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

Add '-0.5' to each side of the equation.
0.5 + -0.5 + x = -10.59481005 + -0.5

Combine like terms: 0.5 + -0.5 = 0.0
0.0 + x = -10.59481005 + -0.5
x = -10.59481005 + -0.5

Combine like terms: -10.59481005 + -0.5 = -11.09481005
x = -11.09481005

Simplifying
x = -11.09481005
