5w2 + -2 = 5w

Reorder the terms:
-2 + 5w2 = 5w

Solving
-2 + 5w2 = 5w

Solving for variable 'w'.

Reorder the terms:
-2 + -5w + 5w2 = 5w + -5w

Combine like terms: 5w + -5w = 0
-2 + -5w + 5w2 = 0

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

Divide each side by '5'.
-0.4 + -1w + w2 = 0

Move the constant term to the right:

Add '0.4' to each side of the equation.
-0.4 + -1w + 0.4 + w2 = 0 + 0.4

Reorder the terms:
-0.4 + 0.4 + -1w + w2 = 0 + 0.4

Combine like terms: -0.4 + 0.4 = 0.0
0.0 + -1w + w2 = 0 + 0.4
-1w + w2 = 0 + 0.4

Combine like terms: 0 + 0.4 = 0.4
-1w + w2 = 0.4

The w term is -1w.  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.
-1w + 0.25 + w2 = 0.4 + 0.25

Reorder the terms:
0.25 + -1w + w2 = 0.4 + 0.25

Combine like terms: 0.4 + 0.25 = 0.65
0.25 + -1w + w2 = 0.65

Factor a perfect square on the left side:
(w + -0.5)(w + -0.5) = 0.65

Calculate the square root of the right side: 0.806225775

Break this problem into two subproblems by setting 
(w + -0.5) equal to 0.806225775 and -0.806225775.

Subproblem 1

w + -0.5 = 0.806225775 Simplifying w + -0.5 = 0.806225775 Reorder the terms: -0.5 + w = 0.806225775 Solving -0.5 + w = 0.806225775 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + w = 0.806225775 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + w = 0.806225775 + 0.5 w = 0.806225775 + 0.5 Combine like terms: 0.806225775 + 0.5 = 1.306225775 w = 1.306225775 Simplifying w = 1.306225775

Subproblem 2

w + -0.5 = -0.806225775 Simplifying w + -0.5 = -0.806225775 Reorder the terms: -0.5 + w = -0.806225775 Solving -0.5 + w = -0.806225775 Solving for variable 'w'. Move all terms containing w to the left, all other terms to the right. Add '0.5' to each side of the equation. -0.5 + 0.5 + w = -0.806225775 + 0.5 Combine like terms: -0.5 + 0.5 = 0.0 0.0 + w = -0.806225775 + 0.5 w = -0.806225775 + 0.5 Combine like terms: -0.806225775 + 0.5 = -0.306225775 w = -0.306225775 Simplifying w = -0.306225775

Solution
