Solution for (1-x)x=0.01 equation:


Simplifying
(1 + -1x) * x = 0.01

Reorder the terms for easier multiplication:
x(1 + -1x) = 0.01
(1 * x + -1x * x) = 0.01
(1x + -1x2) = 0.01

Solving
1x + -1x2 = 0.01

Solving for variable 'x'.

Reorder the terms:
-0.01 + 1x + -1x2 = 0.01 + -0.01

Combine like terms: 0.01 + -0.01 = 0.00
-0.01 + 1x + -1x2 = 0.00

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

Divide each side by '-1'.
0.01 + -1x + x2 = 0.00

Move the constant term to the right:

Add '-0.01' to each side of the equation.
0.01 + -1x + -0.01 + x2 = 0.00 + -0.01

Reorder the terms:
0.01 + -0.01 + -1x + x2 = 0.00 + -0.01

Combine like terms: 0.01 + -0.01 = 0.00
0.00 + -1x + x2 = 0.00 + -0.01
-1x + x2 = 0.00 + -0.01

Combine like terms: 0.00 + -0.01 = -0.01
-1x + x2 = -0.01

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 = -0.01 + 0.25

Reorder the terms:
0.25 + -1x + x2 = -0.01 + 0.25

Combine like terms: -0.01 + 0.25 = 0.24
0.25 + -1x + x2 = 0.24

Factor a perfect square on the left side:
(x + -0.5)(x + -0.5) = 0.24

Calculate the square root of the right side: 0.489897949
