-70 + 2m + -5m2 = 0

Begin completing the square.  Divide all terms by
-5 the coefficient of the squared term: 

Divide each side by '-5'.
14 + -0.4m + m2 = 0

Move the constant term to the right:

Add '-14' to each side of the equation.
14 + -0.4m + -14 + m2 = 0 + -14

Reorder the terms:
14 + -14 + -0.4m + m2 = 0 + -14

Combine like terms: 14 + -14 = 0
0 + -0.4m + m2 = 0 + -14
-0.4m + m2 = 0 + -14

Combine like terms: 0 + -14 = -14
-0.4m + m2 = -14

The m term is -0.4m.  Take half its coefficient (-0.2).
Square it (0.04) and add it to both sides.

Add '0.04' to each side of the equation.
-0.4m + 0.04 + m2 = -14 + 0.04

Reorder the terms:
0.04 + -0.4m + m2 = -14 + 0.04

Combine like terms: -14 + 0.04 = -13.96
0.04 + -0.4m + m2 = -13.96

Factor a perfect square on the left side:
(m + -0.2)(m + -0.2) = -13.96

Can't calculate square root of the right side.

The solution to this equation could not be determined.
