If it's not what You are looking for type in the equation solver your own equation and let us solve it.
a*a+a+6=0
We add all the numbers together, and all the variables
a+a*a+6=0
Wy multiply elements
a^2+a+6=0
a = 1; b = 1; c = +6;
Δ = b2-4ac
Δ = 12-4·1·6
Δ = -23
Delta is less than zero, so there is no solution for the equation
