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

Divide each side by '5'.
2 + -1.8m + m2 = 0

Move the constant term to the right:

Add '-2' to each side of the equation.
2 + -1.8m + -2 + m2 = 0 + -2

Reorder the terms:
2 + -2 + -1.8m + m2 = 0 + -2

Combine like terms: 2 + -2 = 0
0 + -1.8m + m2 = 0 + -2
-1.8m + m2 = 0 + -2

Combine like terms: 0 + -2 = -2
-1.8m + m2 = -2

The m term is -1.8m.  Take half its coefficient (-0.9).
Square it (0.81) and add it to both sides.

Add '0.81' to each side of the equation.
-1.8m + 0.81 + m2 = -2 + 0.81

Reorder the terms:
0.81 + -1.8m + m2 = -2 + 0.81

Combine like terms: -2 + 0.81 = -1.19
0.81 + -1.8m + m2 = -1.19

Factor a perfect square on the left side:
(m + -0.9)(m + -0.9) = -1.19

Can't calculate square root of the right side.
