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

Divide each side by '20'.
-0.3 + 1.15m + m2 = 0

Move the constant term to the right:

Add '0.3' to each side of the equation.
-0.3 + 1.15m + 0.3 + m2 = 0 + 0.3

Reorder the terms:
-0.3 + 0.3 + 1.15m + m2 = 0 + 0.3

Combine like terms: -0.3 + 0.3 = 0.0
0.0 + 1.15m + m2 = 0 + 0.3
1.15m + m2 = 0 + 0.3

Combine like terms: 0 + 0.3 = 0.3
1.15m + m2 = 0.3

The m term is 1.15m.  Take half its coefficient (0.575).
Square it (0.330625) and add it to both sides.

Add '0.330625' to each side of the equation.
1.15m + 0.330625 + m2 = 0.3 + 0.330625

Reorder the terms:
0.330625 + 1.15m + m2 = 0.3 + 0.330625

Combine like terms: 0.3 + 0.330625 = 0.630625
0.330625 + 1.15m + m2 = 0.630625
