s^2+2*s+2=0

Solution for s^2+2*s+2=0 equation:

Simplifying
s2 + 2s + 2 = 0

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

Solving
2 + 2s + s2 = 0

Solving for variable 's'.

Begin completing the square.

Move the constant term to the right:

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

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

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

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

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 = -2 + 1

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

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

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

Can't calculate square root of the right side.
