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

Divide each side by '-5'.
-38.8 + -1x + x2 = 0

Move the constant term to the right:

Add '38.8' to each side of the equation.
-38.8 + -1x + 38.8 + x2 = 0 + 38.8

Reorder the terms:
-38.8 + 38.8 + -1x + x2 = 0 + 38.8

Combine like terms: -38.8 + 38.8 = 0.0
0.0 + -1x + x2 = 0 + 38.8
-1x + x2 = 0 + 38.8

Combine like terms: 0 + 38.8 = 38.8
-1x + x2 = 38.8

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 = 38.8 + 0.25

Reorder the terms:
0.25 + -1x + x2 = 38.8 + 0.25

Combine like terms: 38.8 + 0.25 = 39.05
0.25 + -1x + x2 = 39.05
