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

Divide each side by '-4'.
-0.5 + 0.75m + m2 = 0

Move the constant term to the right:

Add '0.5' to each side of the equation.
-0.5 + 0.75m + 0.5 + m2 = 0 + 0.5

Reorder the terms:
-0.5 + 0.5 + 0.75m + m2 = 0 + 0.5

Combine like terms: -0.5 + 0.5 = 0.0
0.0 + 0.75m + m2 = 0 + 0.5
0.75m + m2 = 0 + 0.5

Combine like terms: 0 + 0.5 = 0.5
0.75m + m2 = 0.5

The m term is 0.75m.  Take half its coefficient (0.375).
Square it (0.140625) and add it to both sides.

Add '0.140625' to each side of the equation.
0.75m + 0.140625 + m2 = 0.5 + 0.140625

Reorder the terms:
0.140625 + 0.75m + m2 = 0.5 + 0.140625

Combine like terms: 0.5 + 0.140625 = 0.640625
0.140625 + 0.75m + m2 = 0.640625

Factor a perfect square on the left side:
(m + 0.375)(m + 0.375) = 0.640625

Calculate the square root of the right side: 0.80039053
