If it's not what You are looking for type in the equation solver your own equation and let us solve it.
s^2+4s^2+8s+12=0
We add all the numbers together, and all the variables
5s^2+8s+12=0
a = 5; b = 8; c = +12;
Δ = b2-4ac
Δ = 82-4·5·12
Δ = -176
Delta is less than zero, so there is no solution for the equation
