x(1-x)-0.25=0

Solution for x(1-x)-0.25=0 equation:

Simplifying
x(1 + -1x) + -0.25 = 0
(1 * x + -1x * x) + -0.25 = 0
(1x + -1x2) + -0.25 = 0

Reorder the terms:
-0.25 + 1x + -1x2 = 0

Solving
-0.25 + 1x + -1x2 = 0

Solving for variable 'x'.

Begin completing the square.  Divide all terms by
-1 the coefficient of the squared term: 

Divide each side by '-1'.
0.25 + -1x + x2 = 0

Move the constant term to the right:

Add '-0.25' to each side of the equation.
0.25 + -1x + -0.25 + x2 = 0 + -0.25

Reorder the terms:
0.25 + -0.25 + -1x + x2 = 0 + -0.25

Combine like terms: 0.25 + -0.25 = 0.00
0.00 + -1x + x2 = 0 + -0.25
-1x + x2 = 0 + -0.25

Combine like terms: 0 + -0.25 = -0.25
-1x + x2 = -0.25

The x term is -1x.  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.
-1x + 0.25 + x2 = -0.25 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -0.25 + 0.25

Combine like terms: -0.25 + 0.25 = 0.00
0.25 + -1x + x2 = 0.00

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = 0.00

Calculate the square root of the right side: 0.00

Break this problem into two subproblems by setting 
(x + -0.5) equal to 0.00 and 0.00.

Subproblem 1
x + -0.5 = 0.00

Simplifying
x + -0.5 = 0.00

Reorder the terms:
-0.5 + x = 0.00

Solving
-0.5 + x = 0.00

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 = 0.00 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + x = 0.00 + 0.5
x = 0.00 + 0.5

Combine like terms: 0.00 + 0.5 = 0.5
x = 0.5

Simplifying
x = 0.5

Subproblem 2
x + -0.5 = 0.00

Simplifying
x + -0.5 = 0.00

Reorder the terms:
-0.5 + x = 0.00

Solving
-0.5 + x = 0.00

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 = 0.00 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + x = 0.00 + 0.5
x = 0.00 + 0.5

Combine like terms: 0.00 + 0.5 = 0.5
x = 0.5

Simplifying
x = 0.5

Solution
The solution to the problem is based on the solutions
from the subproblems.
x = {0.5, 0.5}
