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

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

Move the constant term to the right:

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

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

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

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

The x term is -3.5x.  Take half its coefficient (-1.75).
Square it (3.0625) and add it to both sides.
