Begin completing the square.

Move the constant term to the right:

Add '-12' to each side of the equation.
12 + 11m + -12 + m2 = 0 + -12

Reorder the terms:
12 + -12 + 11m + m2 = 0 + -12

Combine like terms: 12 + -12 = 0
0 + 11m + m2 = 0 + -12
11m + m2 = 0 + -12

Combine like terms: 0 + -12 = -12
11m + m2 = -12

The m term is 11m.  Take half its coefficient (5.5).
Square it (30.25) and add it to both sides.

Add '30.25' to each side of the equation.
11m + 30.25 + m2 = -12 + 30.25

Reorder the terms:
30.25 + 11m + m2 = -12 + 30.25

Combine like terms: -12 + 30.25 = 18.25
30.25 + 11m + m2 = 18.25

Factor a perfect square on the left side:
(m + 5.5)(m + 5.5) = 18.25
