If it's not what You are looking for type in the equation solver your own equation and let us solve it.
X^2+X^2+8X+20=0
We add all the numbers together, and all the variables
2X^2+8X+20=0
a = 2; b = 8; c = +20;
Δ = b2-4ac
Δ = 82-4·2·20
Δ = -96
Delta is less than zero, so there is no solution for the equation
