Solving for variable 'm'.

Begin completing the square.  Divide all terms by
-0.6 the coefficient of the squared term: 

Divide each side by '-0.6'.
-460 + -25m + m2 = 0

Move the constant term to the right:

Add '460' to each side of the equation.
-460 + -25m + 460 + m2 = 0 + 460

Reorder the terms:
-460 + 460 + -25m + m2 = 0 + 460

Combine like terms: -460 + 460 = 0
0 + -25m + m2 = 0 + 460
-25m + m2 = 0 + 460

Combine like terms: 0 + 460 = 460
-25m + m2 = 460

The m term is -25m.  Take half its coefficient (-12.5).
Square it (156.25) and add it to both sides.

Add '156.25' to each side of the equation.
-25m + 156.25 + m2 = 460 + 156.25

Reorder the terms:
156.25 + -25m + m2 = 460 + 156.25

Combine like terms: 460 + 156.25 = 616.25
156.25 + -25m + m2 = 616.25
