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

Divide each side by '2'.
37.5 + 4x + x2 = 0

Move the constant term to the right:

Add '-37.5' to each side of the equation.
37.5 + 4x + -37.5 + x2 = 0 + -37.5

Reorder the terms:
37.5 + -37.5 + 4x + x2 = 0 + -37.5

Combine like terms: 37.5 + -37.5 = 0.0
