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

Divide each side by '5'.
0.4 + -3.4c + c2 = 0

Move the constant term to the right:

Add '-0.4' to each side of the equation.
0.4 + -3.4c + -0.4 + c2 = 0 + -0.4

Reorder the terms:
0.4 + -0.4 + -3.4c + c2 = 0 + -0.4

Combine like terms: 0.4 + -0.4 = 0.0
0.0 + -3.4c + c2 = 0 + -0.4
-3.4c + c2 = 0 + -0.4

Combine like terms: 0 + -0.4 = -0.4
-3.4c + c2 = -0.4

The c term is -3.4c.  Take half its coefficient (-1.7).
Square it (2.89) and add it to both sides.

Add '2.89' to each side of the equation.
-3.4c + 2.89 + c2 = -0.4 + 2.89
