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

Divide each side by '-2'.
-3.5 + -4.5x + x2 = 0

Move the constant term to the right:

Add '3.5' to each side of the equation.
-3.5 + -4.5x + 3.5 + x2 = 0 + 3.5

Reorder the terms:
-3.5 + 3.5 + -4.5x + x2 = 0 + 3.5

Combine like terms: -3.5 + 3.5 = 0.0
0.0 + -4.5x + x2 = 0 + 3.5
-4.5x + x2 = 0 + 3.5

Combine like terms: 0 + 3.5 = 3.5
-4.5x + x2 = 3.5

The x term is -4.5x.  Take half its coefficient (-2.25).
Square it (5.0625) and add it to both sides.
