Solving
7 + -1x + x2 = 3

Solving for variable 'x'.

Reorder the terms:
7 + -3 + -1x + x2 = 3 + -3

Combine like terms: 7 + -3 = 4
4 + -1x + x2 = 3 + -3

Combine like terms: 3 + -3 = 0
4 + -1x + x2 = 0

Begin completing the square.

Move the constant term to the right:

Add '-4' to each side of the equation.
4 + -1x + -4 + x2 = 0 + -4

Reorder the terms:
4 + -4 + -1x + x2 = 0 + -4

Combine like terms: 4 + -4 = 0
0 + -1x + x2 = 0 + -4
-1x + x2 = 0 + -4
