Solving for variable 'm'.

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

Divide each side by '5'.
0.4 + -1.8m + m2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + -1.8m + -0.4 + m2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + -1.8m + m2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + -1.8m + m2 = 0 + -0.4
-1.8m + m2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
-1.8m + m2 = -0.4

The m term is -1.8m.  Take half its coefficient (-0.9).
Square it (0.81) and add it to both sides.

Add '0.81' to each side of the equation.
-1.8m + 0.81 + m2 = -0.4 + 0.81

Reorder the terms:
0.81 + -1.8m + m2 = -0.4 + 0.81

Combine like terms: -0.4 + 0.81 = 0.41
0.81 + -1.8m + m2 = 0.41

Factor a perfect square on the left side:
(m + -0.9)(m + -0.9) = 0.41

Calculate the square root of the right side: 0.640312424

Break this problem into two subproblems by setting 
(m + -0.9) equal to 0.640312424 and -0.640312424.

Subproblem 1

m + -0.9 = 0.640312424 Simplifying m + -0.9 = 0.640312424 Reorder the terms: -0.9 + m = 0.640312424 Solving -0.9 + m = 0.640312424 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '0.9' to each side of the equation. -0.9 + 0.9 + m = 0.640312424 + 0.9 Combine like terms: -0.9 + 0.9 = 0.0 0.0 + m = 0.640312424 + 0.9 m = 0.640312424 + 0.9 Combine like terms: 0.640312424 + 0.9 = 1.540312424 m = 1.540312424 Simplifying m = 1.540312424

Subproblem 2

m + -0.9 = -0.640312424 Simplifying m + -0.9 = -0.640312424 Reorder the terms: -0.9 + m = -0.640312424 Solving -0.9 + m = -0.640312424 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '0.9' to each side of the equation. -0.9 + 0.9 + m = -0.640312424 + 0.9 Combine like terms: -0.9 + 0.9 = 0.0 0.0 + m = -0.640312424 + 0.9 m = -0.640312424 + 0.9 Combine like terms: -0.640312424 + 0.9 = 0.259687576 m = 0.259687576 Simplifying m = 0.259687576
