If it's not what You are looking for type in the equation solver your own equation and let us solve it.
3+4S^2+4S+4=0
We add all the numbers together, and all the variables
4S^2+4S+7=0
a = 4; b = 4; c = +7;
Δ = b2-4ac
Δ = 42-4·4·7
Δ = -96
Delta is less than zero, so there is no solution for the equation
