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
