Solving for variable 'm'.

Begin completing the square.  Divide all terms by
-3 the coefficient of the squared term: 

Divide each side by '-3'.
5.333333333 + -2m + m2 = 0

Move the constant term to the right:

Add '-5.333333333' to each side of the equation.
5.333333333 + -2m + -5.333333333 + m2 = 0 + -5.333333333

Reorder the terms:
5.333333333 + -5.333333333 + -2m + m2 = 0 + -5.333333333

Combine like terms: 5.333333333 + -5.333333333 = 0.000000000
0.000000000 + -2m + m2 = 0 + -5.333333333
-2m + m2 = 0 + -5.333333333

Combine like terms: 0 + -5.333333333 = -5.333333333
-2m + m2 = -5.333333333

The m term is -2m.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2m + 1 + m2 = -5.333333333 + 1

Reorder the terms:
1 + -2m + m2 = -5.333333333 + 1

Combine like terms: -5.333333333 + 1 = -4.333333333
1 + -2m + m2 = -4.333333333

Factor a perfect square on the left side:
(m + -1)(m + -1) = -4.333333333

Can't calculate square root of the right side.
