Solving
103 = 2x + -1x2

Solving for variable 'x'.

Reorder the terms:
103 + -2x + x2 = 2x + -2x + -1x2 + x2

Combine like terms: 2x + -2x = 0
103 + -2x + x2 = 0 + -1x2 + x2
103 + -2x + x2 = -1x2 + x2

Combine like terms: -1x2 + x2 = 0
103 + -2x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-103' to each side of the equation.
103 + -2x + -103 + x2 = 0 + -103

Reorder the terms:
103 + -103 + -2x + x2 = 0 + -103

Combine like terms: 103 + -103 = 0
0 + -2x + x2 = 0 + -103
-2x + x2 = 0 + -103

Combine like terms: 0 + -103 = -103
-2x + x2 = -103

The x term is -2x.  Take half its coefficient (-1).
