If it's not what You are looking for type in the equation solver your own equation and let us solve it.
2X^2+X^2+4X+10=0
We add all the numbers together, and all the variables
3X^2+4X+10=0
a = 3; b = 4; c = +10;
Δ = b2-4ac
Δ = 42-4·3·10
Δ = -104
Delta is less than zero, so there is no solution for the equation
