If it's not what You are looking for type in the equation solver your own equation and let us solve it.
x^2+(1+x)=0
We add all the numbers together, and all the variables
x^2+(x+1)=0
We get rid of parentheses
x^2+x+1=0
a = 1; b = 1; c = +1;
Δ = b2-4ac
Δ = 12-4·1·1
Δ = -3
Delta is less than zero, so there is no solution for the equation
