Solving for variable 'm'.

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

Divide each side by '2'.
1.5625 + 1.5m + m2 = 0

Move the constant term to the right:

Add '-1.5625' to each side of the equation.
1.5625 + 1.5m + -1.5625 + m2 = 0 + -1.5625

Reorder the terms:
1.5625 + -1.5625 + 1.5m + m2 = 0 + -1.5625

Combine like terms: 1.5625 + -1.5625 = 0.0000
0.0000 + 1.5m + m2 = 0 + -1.5625
1.5m + m2 = 0 + -1.5625

Combine like terms: 0 + -1.5625 = -1.5625
1.5m + m2 = -1.5625

The m term is 1.5m.  Take half its coefficient (0.75).
Square it (0.5625) and add it to both sides.

Add '0.5625' to each side of the equation.
1.5m + 0.5625 + m2 = -1.5625 + 0.5625

Reorder the terms:
0.5625 + 1.5m + m2 = -1.5625 + 0.5625

Combine like terms: -1.5625 + 0.5625 = -1
0.5625 + 1.5m + m2 = -1

Factor a perfect square on the left side:
(m + 0.75)(m + 0.75) = -1
