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

Divide each side by '2'.
16.5 + -2.5x + x2 = 0

Move the constant term to the right:

Add '-16.5' to each side of the equation.
16.5 + -2.5x + -16.5 + x2 = 0 + -16.5

Reorder the terms:
16.5 + -16.5 + -2.5x + x2 = 0 + -16.5

Combine like terms: 16.5 + -16.5 = 0.0
0.0 + -2.5x + x2 = 0 + -16.5
-2.5x + x2 = 0 + -16.5

Combine like terms: 0 + -16.5 = -16.5
-2.5x + x2 = -16.5

The x term is -2.5x.  Take half its coefficient (-1.25).
Square it (1.5625) and add it to both sides.

Add '1.5625' to each side of the equation.
-2.5x + 1.5625 + x2 = -16.5 + 1.5625

Reorder the terms:
1.5625 + -2.5x + x2 = -16.5 + 1.5625

Combine like terms: -16.5 + 1.5625 = -14.9375
1.5625 + -2.5x + x2 = -14.9375

Factor a perfect square on the left side:
(x + -1.25)(x + -1.25) = -14.9375

Can't calculate square root of the right side.
