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

Divide each side by '5'.
0.6 + 3.4x + x2 = 0

Move the constant term to the right:

Add '-0.6' to each side of the equation.
0.6 + 3.4x + -0.6 + x2 = 0 + -0.6

Reorder the terms:
0.6 + -0.6 + 3.4x + x2 = 0 + -0.6

Combine like terms: 0.6 + -0.6 = 0.0
0.0 + 3.4x + x2 = 0 + -0.6
3.4x + x2 = 0 + -0.6

Combine like terms: 0 + -0.6 = -0.6
3.4x + x2 = -0.6

The x term is 3.4x.  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.
3.4x + 2.89 + x2 = -0.6 + 2.89

Reorder the terms:
2.89 + 3.4x + x2 = -0.6 + 2.89

Combine like terms: -0.6 + 2.89 = 2.29
2.89 + 3.4x + x2 = 2.29
