Simplifying
2.4m(m + -3) + 3.8 = -8.2

Reorder the terms:
2.4m(-3 + m) + 3.8 = -8.2
(-3 * 2.4m + m * 2.4m) + 3.8 = -8.2
(-7.2m + 2.4m2) + 3.8 = -8.2

Reorder the terms:
3.8 + -7.2m + 2.4m2 = -8.2

Solving
3.8 + -7.2m + 2.4m2 = -8.2

Solving for variable 'm'.

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

Divide each side by '2.4'.
5 + -3m + m2 = 0

Move the constant term to the right:

Add '-5' to each side of the equation.
5 + -3m + -5 + m2 = 0 + -5

Reorder the terms:
5 + -5 + -3m + m2 = 0 + -5

Combine like terms: 5 + -5 = 0
0 + -3m + m2 = 0 + -5
-3m + m2 = 0 + -5

Combine like terms: 0 + -5 = -5
-3m + m2 = -5

The m term is -3m.  Take half its coefficient (-1.5).
Square it (2.25) and add it to both sides.

Add '2.25' to each side of the equation.
-3m + 2.25 + m2 = -5 + 2.25

Reorder the terms:
2.25 + -3m + m2 = -5 + 2.25

Combine like terms: -5 + 2.25 = -2.75
2.25 + -3m + m2 = -2.75

Factor a perfect square on the left side:
(m + -1.5)(m + -1.5) = -2.75
