Begin completing the square.  Divide all terms by
-50 the coefficient of the squared term: 

Divide each side by '-50'.
-0.54 + 0.18m + m2 = 0.0

Move the constant term to the right:

Add '0.54' to each side of the equation.
-0.54 + 0.18m + 0.54 + m2 = 0.0 + 0.54

Reorder the terms:
-0.54 + 0.54 + 0.18m + m2 = 0.0 + 0.54

Combine like terms: -0.54 + 0.54 = 0.00
0.00 + 0.18m + m2 = 0.0 + 0.54
0.18m + m2 = 0.0 + 0.54

Combine like terms: 0.0 + 0.54 = 0.54
0.18m + m2 = 0.54

The m term is 0.18m.  Take half its coefficient (0.09).
Square it (0.0081) and add it to both sides.

Add '0.0081' to each side of the equation.
0.18m + 0.0081 + m2 = 0.54 + 0.0081

Reorder the terms:
0.0081 + 0.18m + m2 = 0.54 + 0.0081

Combine like terms: 0.54 + 0.0081 = 0.5481
0.0081 + 0.18m + m2 = 0.5481

Factor a perfect square on the left side:
(m + 0.09)(m + 0.09) = 0.5481

Calculate the square root of the right side: 0.740337761

(m + 0.09) equal to 0.740337761 and -0.740337761.

Subproblem 1

m + 0.09 = 0.740337761 Simplifying m + 0.09 = 0.740337761 Reorder the terms: 0.09 + m = 0.740337761 Solving 0.09 + m = 0.740337761 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.09' to each side of the equation. 0.09 + -0.09 + m = 0.740337761 + -0.09 Combine like terms: 0.09 + -0.09 = 0.00 0.00 + m = 0.740337761 + -0.09 m = 0.740337761 + -0.09 Combine like terms: 0.740337761 + -0.09 = 0.650337761 m = 0.650337761 Simplifying m = 0.650337761

Subproblem 2

m + 0.09 = -0.740337761 Simplifying m + 0.09 = -0.740337761 Reorder the terms: 0.09 + m = -0.740337761 Solving 0.09 + m = -0.740337761 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.09' to each side of the equation. 0.09 + -0.09 + m = -0.740337761 + -0.09 Combine like terms: 0.09 + -0.09 = 0.00 0.00 + m = -0.740337761 + -0.09 m = -0.740337761 + -0.09 Combine like terms: -0.740337761 + -0.09 = -0.830337761 m = -0.830337761 Simplifying m = -0.830337761
