37 + -20x + 4x2 = 28x + -28x + -4x2 + 4x2

Combine like terms: 28x + -28x = 0
37 + -20x + 4x2 = 0 + -4x2 + 4x2
37 + -20x + 4x2 = -4x2 + 4x2

Combine like terms: -4x2 + 4x2 = 0
37 + -20x + 4x2 = 0

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

Divide each side by '4'.
9.25 + -5x + x2 = 0

Move the constant term to the right:

Add '-9.25' to each side of the equation.
9.25 + -5x + -9.25 + x2 = 0 + -9.25

Reorder the terms:
9.25 + -9.25 + -5x + x2 = 0 + -9.25

Combine like terms: 9.25 + -9.25 = 0.00
0.00 + -5x + x2 = 0 + -9.25
-5x + x2 = 0 + -9.25

Combine like terms: 0 + -9.25 = -9.25
-5x + x2 = -9.25

The x term is -5x.  Take half its coefficient (-2.5).
