(s^2+s+1)=0

Solution for (s^2+s+1)=0 equation:

Simplifying
(s2 + s + 1) = 0

Reorder the terms:
(1 + s + s2) = 0

Remove parenthesis around (1 + s + s2)
1 + s + s2 = 0

Solving
1 + s + s2 = 0

Solving for variable 's'.

Begin completing the square.

Move the constant term to the right:

Add '-1' to each side of the equation.
1 + s + -1 + s2 = 0 + -1

Reorder the terms:
1 + -1 + s + s2 = 0 + -1

Combine like terms: 1 + -1 = 0
0 + s + s2 = 0 + -1
s + s2 = 0 + -1

Combine like terms: 0 + -1 = -1
s + s2 = -1

The s term is s.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
s + 0.25 + s2 = -1 + 0.25

Reorder the terms:
0.25 + s + s2 = -1 + 0.25

Combine like terms: -1 + 0.25 = -0.75
0.25 + s + s2 = -0.75

Factor a perfect square on the left side:
(s + 0.5)(s + 0.5) = -0.75

Can't calculate square root of the right side.

The solution to this equation could not be determined.
