Solving for variable 'm'.

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

Divide each side by '5'.
1.2 + 2.4m + m2 = 0

Move the constant term to the right:

Add '-1.2' to each side of the equation.
1.2 + 2.4m + -1.2 + m2 = 0 + -1.2

Reorder the terms:
1.2 + -1.2 + 2.4m + m2 = 0 + -1.2

Combine like terms: 1.2 + -1.2 = 0.0
0.0 + 2.4m + m2 = 0 + -1.2
2.4m + m2 = 0 + -1.2

Combine like terms: 0 + -1.2 = -1.2
2.4m + m2 = -1.2

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 = -1.2 + 1.44

Reorder the terms:
1.44 + 2.4m + m2 = -1.2 + 1.44

Combine like terms: -1.2 + 1.44 = 0.24
1.44 + 2.4m + m2 = 0.24

Factor a perfect square on the left side:
(m + 1.2)(m + 1.2) = 0.24

Calculate the square root of the right side: 0.489897949
