Solving for variable 'm'.

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
-20.5 + m + m2 = 0

Move the constant term to the right:

Add '20.5' to each side of the equation.
-20.5 + m + 20.5 + m2 = 0 + 20.5

Reorder the terms:
-20.5 + 20.5 + m + m2 = 0 + 20.5

Combine like terms: -20.5 + 20.5 = 0.0
0.0 + m + m2 = 0 + 20.5
m + m2 = 0 + 20.5

Combine like terms: 0 + 20.5 = 20.5
m + m2 = 20.5

The m term is m.  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.
 + 0.25 + m2 = 20.5 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + m2 = 20.5 + 0.25

Combine like terms: 20.5 + 0.25 = 20.75
1.25 + m2 = 20.75

Factor a perfect square on the left side:
(m + 0.5)(m + 0.5) = 20.75

Calculate the square root of the right side: 4.55521679

Break this problem into two subproblems by setting 
(m + 0.5) equal to 4.55521679 and -4.55521679.

Subproblem 1

m + 0.5 = 4.55521679 Simplifying m + 0.5 = 4.55521679 Reorder the terms: 0.5 + m = 4.55521679 Solving 0.5 + m = 4.55521679 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.5' to each side of the equation. 0.5 + -0.5 + m = 4.55521679 + -0.5 Combine like terms: 0.5 + -0.5 = 0.0 0.0 + m = 4.55521679 + -0.5 m = 4.55521679 + -0.5 Combine like terms: 4.55521679 + -0.5 = 4.05521679 m = 4.05521679 Simplifying m = 4.05521679
