If it's not what You are looking for type in the equation solver your own equation and let us solve it.
X2+X2+6X+40=0
We add all the numbers together, and all the variables
2X^2+6X+40=0
a = 2; b = 6; c = +40;
Δ = b2-4ac
Δ = 62-4·2·40
Δ = -284
Delta is less than zero, so there is no solution for the equation
