Solving for variable 'm'.

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

Divide each side by '5'.
-2 + -0.6m + m2 = 0

Move the constant term to the right:

Add '2' to each side of the equation.
-2 + -0.6m + 2 + m2 = 0 + 2

Reorder the terms:
-2 + 2 + -0.6m + m2 = 0 + 2

Combine like terms: -2 + 2 = 0
0 + -0.6m + m2 = 0 + 2
-0.6m + m2 = 0 + 2

Combine like terms: 0 + 2 = 2
-0.6m + m2 = 2

The m term is -0.6m.  Take half its coefficient (-0.3).
Square it (0.09) and add it to both sides.

Add '0.09' to each side of the equation.
-0.6m + 0.09 + m2 = 2 + 0.09

Reorder the terms:
0.09 + -0.6m + m2 = 2 + 0.09

Combine like terms: 2 + 0.09 = 2.09
0.09 + -0.6m + m2 = 2.09

Factor a perfect square on the left side:
(m + -0.3)(m + -0.3) = 2.09

Calculate the square root of the right side: 1.445683229

Break this problem into two subproblems by setting 
(m + -0.3) equal to 1.445683229 and -1.445683229.

Subproblem 1

m + -0.3 = 1.445683229 Simplifying m + -0.3 = 1.445683229 Reorder the terms: -0.3 + m = 1.445683229 Solving -0.3 + m = 1.445683229 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '0.3' to each side of the equation. -0.3 + 0.3 + m = 1.445683229 + 0.3 Combine like terms: -0.3 + 0.3 = 0.0 0.0 + m = 1.445683229 + 0.3 m = 1.445683229 + 0.3 Combine like terms: 1.445683229 + 0.3 = 1.745683229 m = 1.745683229 Simplifying m = 1.745683229
