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

Divide each side by '5'.
-5.8 + 1.4x + x2 = 0

Move the constant term to the right:

Add '5.8' to each side of the equation.
-5.8 + 1.4x + 5.8 + x2 = 0 + 5.8

Reorder the terms:
-5.8 + 5.8 + 1.4x + x2 = 0 + 5.8

Combine like terms: -5.8 + 5.8 = 0.0
0.0 + 1.4x + x2 = 0 + 5.8
1.4x + x2 = 0 + 5.8

Combine like terms: 0 + 5.8 = 5.8
1.4x + x2 = 5.8

The x term is 1.4x.  Take half its coefficient (0.7).
Square it (0.49) and add it to both sides.

Add '0.49' to each side of the equation.
1.4x + 0.49 + x2 = 5.8 + 0.49

Reorder the terms:
0.49 + 1.4x + x2 = 5.8 + 0.49

Combine like terms: 5.8 + 0.49 = 6.29
0.49 + 1.4x + x2 = 6.29
