Solving
4m2 = -15 + 12m

Solving for variable 'm'.

Reorder the terms:
15 + -12m + 4m2 = -15 + 12m + 15 + -12m

Reorder the terms:
15 + -12m + 4m2 = -15 + 15 + 12m + -12m

Combine like terms: -15 + 15 = 0
15 + -12m + 4m2 = 0 + 12m + -12m
15 + -12m + 4m2 = 12m + -12m

Combine like terms: 12m + -12m = 0
15 + -12m + 4m2 = 0

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

Divide each side by '4'.
3.75 + -3m + m2 = 0

Move the constant term to the right:

Add '-3.75' to each side of the equation.
3.75 + -3m + -3.75 + m2 = 0 + -3.75

Reorder the terms:
3.75 + -3.75 + -3m + m2 = 0 + -3.75

Combine like terms: 3.75 + -3.75 = 0.00
0.00 + -3m + m2 = 0 + -3.75
-3m + m2 = 0 + -3.75

Combine like terms: 0 + -3.75 = -3.75
-3m + m2 = -3.75

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 = -3.75 + 2.25

Reorder the terms:
2.25 + -3m + m2 = -3.75 + 2.25

Combine like terms: -3.75 + 2.25 = -1.5
2.25 + -3m + m2 = -1.5

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

Can't calculate square root of the right side.

The solution to this equation could not be determined.
