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

Divide each side by '-5'.
1.4 + -1x + x2 = 0

Move the constant term to the right:

Add '-1.4' to each side of the equation.
1.4 + -1x + -1.4 + x2 = 0 + -1.4

Reorder the terms:
1.4 + -1.4 + -1x + x2 = 0 + -1.4

Combine like terms: 1.4 + -1.4 = 0.0
0.0 + -1x + x2 = 0 + -1.4
-1x + x2 = 0 + -1.4

Combine like terms: 0 + -1.4 = -1.4
-1x + x2 = -1.4

The x term is -1x.  Take half its coefficient (-0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
-1x + 0.25 + x2 = -1.4 + 0.25
