Solution for 0.8=3.2x(1-x) equation:


Simplifying
0.8 = 3.2x(1 + -1x)
0.8 = (1 * 3.2x + -1x * 3.2x)
0.8 = (3.2x + -3.2x2)

Solving
0.8 = 3.2x + -3.2x2

Solving for variable 'x'.

Reorder the terms:
0.8 + -3.2x + 3.2x2 = 3.2x + -3.2x + -3.2x2 + 3.2x2

Combine like terms: 3.2x + -3.2x = 0.0
0.8 + -3.2x + 3.2x2 = 0.0 + -3.2x2 + 3.2x2
0.8 + -3.2x + 3.2x2 = -3.2x2 + 3.2x2

Combine like terms: -3.2x2 + 3.2x2 = 0.0
0.8 + -3.2x + 3.2x2 = 0.0

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

Divide each side by '3.2'.
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}
