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

Divide each side by '-2'.
155 + -8.5x + x2 = 0

Move the constant term to the right:

Add '-155' to each side of the equation.
155 + -8.5x + -155 + x2 = 0 + -155

Reorder the terms:
155 + -155 + -8.5x + x2 = 0 + -155

Combine like terms: 155 + -155 = 0
0 + -8.5x + x2 = 0 + -155
-8.5x + x2 = 0 + -155

Combine like terms: 0 + -155 = -155
-8.5x + x2 = -155

The x term is -8.5x.  Take half its coefficient (-4.25).
Square it (18.0625) and add it to both sides.

Add '18.0625' to each side of the equation.
-8.5x + 18.0625 + x2 = -155 + 18.0625

Reorder the terms:
18.0625 + -8.5x + x2 = -155 + 18.0625

Combine like terms: -155 + 18.0625 = -136.9375
18.0625 + -8.5x + x2 = -136.9375

Factor a perfect square on the left side:
(x + -4.25)(x + -4.25) = -136.9375

Can't calculate square root of the right side.
