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

Divide each side by '8'.
-1.375 + -0.125m + m2 = 0

Move the constant term to the right:

Add '1.375' to each side of the equation.
-1.375 + -0.125m + 1.375 + m2 = 0 + 1.375

Reorder the terms:
-1.375 + 1.375 + -0.125m + m2 = 0 + 1.375

Combine like terms: -1.375 + 1.375 = 0.000
0.000 + -0.125m + m2 = 0 + 1.375
-0.125m + m2 = 0 + 1.375

Combine like terms: 0 + 1.375 = 1.375
-0.125m + m2 = 1.375

The m term is -0.125m.  Take half its coefficient (-0.0625).
Square it (0.00390625) and add it to both sides.
