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

Divide each side by '5'.
-1.2 + 0.4m + m2 = 0

Move the constant term to the right:

Add '1.2' to each side of the equation.
-1.2 + 0.4m + 1.2 + m2 = 0 + 1.2

Reorder the terms:
-1.2 + 1.2 + 0.4m + m2 = 0 + 1.2

Combine like terms: -1.2 + 1.2 = 0.0
0.0 + 0.4m + m2 = 0 + 1.2
0.4m + m2 = 0 + 1.2

Combine like terms: 0 + 1.2 = 1.2
0.4m + m2 = 1.2

The m term is 0.4m.  Take half its coefficient (0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
0.4m + 0.04 + m2 = 1.2 + 0.04

Reorder the terms:
0.04 + 0.4m + m2 = 1.2 + 0.04

Combine like terms: 1.2 + 0.04 = 1.24
0.04 + 0.4m + m2 = 1.24

Factor a perfect square on the left side:
(m + 0.2)(m + 0.2) = 1.24

Calculate the square root of the right side: 1.113552873

Break this problem into two subproblems by setting 
(m + 0.2) equal to 1.113552873 and -1.113552873.

Subproblem 1

m + 0.2 = 1.113552873 Simplifying m + 0.2 = 1.113552873 Reorder the terms: 0.2 + m = 1.113552873 Solving 0.2 + m = 1.113552873 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.2' to each side of the equation. 0.2 + -0.2 + m = 1.113552873 + -0.2 Combine like terms: 0.2 + -0.2 = 0.0 0.0 + m = 1.113552873 + -0.2 m = 1.113552873 + -0.2 Combine like terms: 1.113552873 + -0.2 = 0.913552873 m = 0.913552873 Simplifying m = 0.913552873
