17 + -4x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-17' to each side of the equation.
17 + -4x + -17 + x2 = 0 + -17

Reorder the terms:
17 + -17 + -4x + x2 = 0 + -17

Combine like terms: 17 + -17 = 0
0 + -4x + x2 = 0 + -17
-4x + x2 = 0 + -17

Combine like terms: 0 + -17 = -17
-4x + x2 = -17

The x term is -4x.  Take half its coefficient (-2).
Square it (4) and add it to both sides.
