Solving for variable 's'.

Begin completing the square.

Move the constant term to the right:

Add '-16' to each side of the equation.
16 + 6s + -16 + s2 = 0 + -16

Reorder the terms:
16 + -16 + 6s + s2 = 0 + -16

Combine like terms: 16 + -16 = 0
0 + 6s + s2 = 0 + -16
6s + s2 = 0 + -16

Combine like terms: 0 + -16 = -16
6s + s2 = -16

The s term is 6s.  Take half its coefficient (3).
Square it (9) and add it to both sides.

Add '9' to each side of the equation.
6s + 9 + s2 = -16 + 9

Reorder the terms:
9 + 6s + s2 = -16 + 9

Combine like terms: -16 + 9 = -7
9 + 6s + s2 = -7

Factor a perfect square on the left side:
(s + 3)(s + 3) = -7

Can't calculate square root of the right side.
