Solving for variable 'm'.

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

Divide each side by '8'.
2 + 0.625m + m2 = 0

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + 0.625m + -2 + m2 = 0 + -2

Reorder the terms:
2 + -2 + 0.625m + m2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + 0.625m + m2 = 0 + -2
0.625m + m2 = 0 + -2

Combine like terms: 0 + -2 = -2
0.625m + m2 = -2

The m term is 0.625m.  Take half its coefficient (0.3125).
