(6 * 2m + -1m * 2m) = 3
(12m + -2m2) = 3

Solving
12m + -2m2 = 3

Solving for variable 'm'.

Reorder the terms:
-3 + 12m + -2m2 = 3 + -3

Combine like terms: 3 + -3 = 0
-3 + 12m + -2m2 = 0

Begin completing the square.  Divide all terms by
-2 the coefficient of the squared term: 

Divide each side by '-2'.
1.5 + -6m + m2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + -6m + -1.5 + m2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + -6m + m2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + -6m + m2 = 0 + -1.5
-6m + m2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
-6m + m2 = -1.5

The m term is -6m.  Take half its coefficient (-3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
-6m + 9 + m2 = -1.5 + 9

Reorder the terms:
9 + -6m + m2 = -1.5 + 9

Combine like terms: -1.5 + 9 = 7.5
9 + -6m + m2 = 7.5

Factor a perfect square on the left side:
(m + -3)(m + -3) = 7.5
