Divide each side by '4'.
-2.75 + 1.25m + m2 = 0

Move the constant term to the right:

Add '2.75' to each side of the equation.
-2.75 + 1.25m + 2.75 + m2 = 0 + 2.75

Reorder the terms:
-2.75 + 2.75 + 1.25m + m2 = 0 + 2.75

Combine like terms: -2.75 + 2.75 = 0.00
0.00 + 1.25m + m2 = 0 + 2.75
1.25m + m2 = 0 + 2.75

Combine like terms: 0 + 2.75 = 2.75
1.25m + m2 = 2.75

The m term is 1.25m.  Take half its coefficient (0.625).
Square it (0.390625) and add it to both sides.

Add '0.390625' to each side of the equation.
1.25m + 0.390625 + m2 = 2.75 + 0.390625

Reorder the terms:
0.390625 + 1.25m + m2 = 2.75 + 0.390625

Combine like terms: 2.75 + 0.390625 = 3.140625
0.390625 + 1.25m + m2 = 3.140625
