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

Divide each side by '8'.
1.125 + -0.75m + m2 = 0

Move the constant term to the right:

Add '-1.125' to each side of the equation.
1.125 + -0.75m + -1.125 + m2 = 0 + -1.125

Reorder the terms:
1.125 + -1.125 + -0.75m + m2 = 0 + -1.125

Combine like terms: 1.125 + -1.125 = 0.000
0.000 + -0.75m + m2 = 0 + -1.125
-0.75m + m2 = 0 + -1.125

Combine like terms: 0 + -1.125 = -1.125
-0.75m + m2 = -1.125

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 = -1.125 + 0.140625

Reorder the terms:
0.140625 + -0.75m + m2 = -1.125 + 0.140625

Combine like terms: -1.125 + 0.140625 = -0.984375
0.140625 + -0.75m + m2 = -0.984375
