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 + 2.4m + m2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + 2.4m + -0.4 + m2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + 2.4m + m2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + 2.4m + m2 = 0 + -0.4
2.4m + m2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
2.4m + m2 = -0.4

The m term is 2.4m.  Take half its coefficient (1.2).
Square it (1.44) and add it to both sides.

Add '1.44' to each side of the equation.
2.4m + 1.44 + m2 = -0.4 + 1.44

Reorder the terms:
1.44 + 2.4m + m2 = -0.4 + 1.44

Combine like terms: -0.4 + 1.44 = 1.04
1.44 + 2.4m + m2 = 1.04

Factor a perfect square on the left side:
(m + 1.2)(m + 1.2) = 1.04

Calculate the square root of the right side: 1.019803903

Break this problem into two subproblems by setting 
(m + 1.2) equal to 1.019803903 and -1.019803903.

Subproblem 1

m + 1.2 = 1.019803903 Simplifying m + 1.2 = 1.019803903 Reorder the terms: 1.2 + m = 1.019803903 Solving 1.2 + m = 1.019803903 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + m = 1.019803903 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + m = 1.019803903 + -1.2 m = 1.019803903 + -1.2 Combine like terms: 1.019803903 + -1.2 = -0.180196097 m = -0.180196097 Simplifying m = -0.180196097

Subproblem 2

m + 1.2 = -1.019803903 Simplifying m + 1.2 = -1.019803903 Reorder the terms: 1.2 + m = -1.019803903 Solving 1.2 + m = -1.019803903 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-1.2' to each side of the equation. 1.2 + -1.2 + m = -1.019803903 + -1.2 Combine like terms: 1.2 + -1.2 = 0.0 0.0 + m = -1.019803903 + -1.2 m = -1.019803903 + -1.2 Combine like terms: -1.019803903 + -1.2 = -2.219803903 m = -2.219803903 Simplifying m = -2.219803903

Solution
