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

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

Move the constant term to the right:

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

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

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

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

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 = 1.5 + 0.5625

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

Combine like terms: 1.5 + 0.5625 = 2.0625
0.5625 + -1.5m + m2 = 2.0625

Factor a perfect square on the left side:
(m + -0.75)(m + -0.75) = 2.0625

Calculate the square root of the right side: 1.436140662
