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

Divide each side by '4'.
-1.5 + -0.25m + m2 = 0

Move the constant term to the right:

Add '1.5' to each side of the equation.
-1.5 + -0.25m + 1.5 + m2 = 0 + 1.5

Reorder the terms:
-1.5 + 1.5 + -0.25m + m2 = 0 + 1.5

Combine like terms: -1.5 + 1.5 = 0.0
0.0 + -0.25m + m2 = 0 + 1.5
-0.25m + m2 = 0 + 1.5

Combine like terms: 0 + 1.5 = 1.5
-0.25m + m2 = 1.5

The m term is -0.25m.  Take half its coefficient (-0.125).
Square it (0.015625) and add it to both sides.

Add '0.015625' to each side of the equation.
-0.25m + 0.015625 + m2 = 1.5 + 0.015625

Reorder the terms:
0.015625 + -0.25m + m2 = 1.5 + 0.015625

Combine like terms: 1.5 + 0.015625 = 1.515625
0.015625 + -0.25m + m2 = 1.515625

Factor a perfect square on the left side:
(m + -0.125)(m + -0.125) = 1.515625
