If it's not what You are looking for type in the equation solver your own equation and let us solve it.
x2+0.3x+0.5=0
We add all the numbers together, and all the variables
x^2+0.3x+0.5=0
a = 1; b = 0.3; c = +0.5;
Δ = b2-4ac
Δ = 0.32-4·1·0.5
Δ = -1.91
Delta is less than zero, so there is no solution for the equation
