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

Divide each side by '10'.
-1.1 + 0.2m + m2 = 0

Move the constant term to the right:

Add '1.1' to each side of the equation.
-1.1 + 0.2m + 1.1 + m2 = 0 + 1.1

Reorder the terms:
-1.1 + 1.1 + 0.2m + m2 = 0 + 1.1

Combine like terms: -1.1 + 1.1 = 0.0
0.0 + 0.2m + m2 = 0 + 1.1
0.2m + m2 = 0 + 1.1

Combine like terms: 0 + 1.1 = 1.1
0.2m + m2 = 1.1

The m term is 0.2m.  Take half its coefficient (0.1).
Square it (0.01) and add it to both sides.

Add '0.01' to each side of the equation.
0.2m + 0.01 + m2 = 1.1 + 0.01

Reorder the terms:
0.01 + 0.2m + m2 = 1.1 + 0.01

Combine like terms: 1.1 + 0.01 = 1.11
0.01 + 0.2m + m2 = 1.11

Factor a perfect square on the left side:
(m + 0.1)(m + 0.1) = 1.11

Calculate the square root of the right side: 1.053565375

(m + 0.1) equal to 1.053565375 and -1.053565375.

Subproblem 1

m + 0.1 = 1.053565375 Simplifying m + 0.1 = 1.053565375 Reorder the terms: 0.1 + m = 1.053565375 Solving 0.1 + m = 1.053565375 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.1' to each side of the equation. 0.1 + -0.1 + m = 1.053565375 + -0.1 Combine like terms: 0.1 + -0.1 = 0.0 0.0 + m = 1.053565375 + -0.1 m = 1.053565375 + -0.1 Combine like terms: 1.053565375 + -0.1 = 0.953565375 m = 0.953565375 Simplifying m = 0.953565375

Subproblem 2

m + 0.1 = -1.053565375 Simplifying m + 0.1 = -1.053565375 Reorder the terms: 0.1 + m = -1.053565375 Solving 0.1 + m = -1.053565375 Solving for variable 'm'. Move all terms containing m to the left, all other terms to the right. Add '-0.1' to each side of the equation. 0.1 + -0.1 + m = -1.053565375 + -0.1 Combine like terms: 0.1 + -0.1 = 0.0 0.0 + m = -1.053565375 + -0.1 m = -1.053565375 + -0.1 Combine like terms: -1.053565375 + -0.1 = -1.153565375 m = -1.153565375 Simplifying m = -1.153565375
