Solution for 7-10w=w(1-w) equation:


Simplifying
7 + -10w = w(1 + -1w)
7 + -10w = (1 * w + -1w * w)
7 + -10w = (1w + -1w2)

Solving
7 + -10w = 1w + -1w2

Solving for variable 'w'.

Combine like terms: -10w + -1w = -11w
7 + -11w + w2 = 1w + -1w2 + -1w + w2

Reorder the terms:
7 + -11w + w2 = 1w + -1w + -1w2 + w2

Combine like terms: 1w + -1w = 0
7 + -11w + w2 = 0 + -1w2 + w2
7 + -11w + w2 = -1w2 + w2

Combine like terms: -1w2 + w2 = 0
7 + -11w + w2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-7' to each side of the equation.
7 + -11w + -7 + w2 = 0 + -7

Reorder the terms:
7 + -7 + -11w + w2 = 0 + -7

Combine like terms: 7 + -7 = 0
0 + -11w + w2 = 0 + -7
-11w + w2 = 0 + -7

Combine like terms: 0 + -7 = -7
-11w + w2 = -7

The w term is -11w.  Take half its coefficient (-5.5).
Square it (30.25) and add it to both sides.

Add '30.25' to each side of the equation.
-11w + 30.25 + w2 = -7 + 30.25

Reorder the terms:
30.25 + -11w + w2 = -7 + 30.25

Combine like terms: -7 + 30.25 = 23.25
30.25 + -11w + w2 = 23.25

Factor a perfect square on the left side:
(w + -5.5)(w + -5.5) = 23.25

Calculate the square root of the right side: 4.82182538

Break this problem into two subproblems by setting 
(w + -5.5) equal to 4.82182538 and -4.82182538.

Subproblem 1

w + -5.5 = 4.82182538 Simplifying w + -5.5 = 4.82182538 Reorder the terms: -5.5 + w = 4.82182538 Solving -5.5 + w = 4.82182538 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '5.5' to each side of the equation. -5.5 + 5.5 + w = 4.82182538 + 5.5 Combine like terms: -5.5 + 5.5 = 0.0 0.0 + w = 4.82182538 + 5.5 w = 4.82182538 + 5.5 Combine like terms: 4.82182538 + 5.5 = 10.32182538 w = 10.32182538 Simplifying w = 10.32182538
