7 + -2s + s2 = 0

Solving
7 + -2s + s2 = 0

Solving for variable 's'.

Begin completing the square.

Move the constant term to the right:

Add '-7' to each side of the equation.
7 + -2s + -7 + s2 = 0 + -7

Reorder the terms:
7 + -7 + -2s + s2 = 0 + -7

Combine like terms: 7 + -7 = 0
0 + -2s + s2 = 0 + -7
-2s + s2 = 0 + -7

Combine like terms: 0 + -7 = -7
-2s + s2 = -7

The s term is -2s.  Take half its coefficient (-1).
Square it (1) and add it to both sides.

Add '1' to each side of the equation.
-2s + 1 + s2 = -7 + 1

Reorder the terms:
1 + -2s + s2 = -7 + 1

Combine like terms: -7 + 1 = -6
1 + -2s + s2 = -6

Factor a perfect square on the left side:
(s + -1)(s + -1) = -6

Can't calculate square root of the right side.
