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

Divide each side by '2'.
15.5 + 0.5X + X2 = 0

Move the constant term to the right:

Add '-15.5' to each side of the equation.
15.5 + 0.5X + -15.5 + X2 = 0 + -15.5

Reorder the terms:
15.5 + -15.5 + 0.5X + X2 = 0 + -15.5

Combine like terms: 15.5 + -15.5 = 0.0
0.0 + 0.5X + X2 = 0 + -15.5
0.5X + X2 = 0 + -15.5

Combine like terms: 0 + -15.5 = -15.5
0.5X + X2 = -15.5

The X term is 0.5X.  Take half its coefficient (0.25).
Square it (0.0625) and add it to both sides.

Add '0.0625' to each side of the equation.
0.5X + 0.0625 + X2 = -15.5 + 0.0625

Reorder the terms:
0.0625 + 0.5X + X2 = -15.5 + 0.0625

Combine like terms: -15.5 + 0.0625 = -15.4375
0.0625 + 0.5X + X2 = -15.4375

Factor a perfect square on the left side:
(X + 0.25)(X + 0.25) = -15.4375

Can't calculate square root of the right side.
