Solving for variable 'm'.

Begin completing the square.

Move the constant term to the right:

Add '15' to each side of the equation.
-15 + 1m + 15 + m2 = 0 + 15

Reorder the terms:
-15 + 15 + 1m + m2 = 0 + 15

Combine like terms: -15 + 15 = 0
0 + 1m + m2 = 0 + 15
1m + m2 = 0 + 15

Combine like terms: 0 + 15 = 15
1m + m2 = 15

The m term is 1m.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
m + 0.25 + m2 = 15 + 0.25

Reorder the terms:
0.25 + m + m2 = 15 + 0.25

Combine like terms: 15 + 0.25 = 15.25
0.25 + m + m2 = 15.25

Factor a perfect square on the left side:
(m + 0.5)(m + 0.5) = 15.25

Calculate the square root of the right side: 3.905124838
