If it's not what You are looking for type in the equation solver your own equation and let us solve it.
z^2+9z^2+20=0
We add all the numbers together, and all the variables
10z^2+20=0
a = 10; b = 0; c = +20;
Δ = b2-4ac
Δ = 02-4·10·20
Δ = -800
Delta is less than zero, so there is no solution for the equation
