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

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

Move the constant term to the right:

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

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

Combine like terms: -1.5 + 1.5 = 0.0
0.0 + m + m2 = 0 + 1.5
m + m2 = 0 + 1.5

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

The m term is m.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
 + 0.25 + m2 = 1.5 + 0.25

Combine like terms:  + 0.25 = 1.25
1.25 + m2 = 1.5 + 0.25

Combine like terms: 1.5 + 0.25 = 1.75
1.25 + m2 = 1.75

Factor a perfect square on the left side:
(m + 0.5)(m + 0.5) = 1.75
