If it's not what You are looking for type in the equation solver your own equation and let us solve it.
y^2-y+1/2=0
We add all the numbers together, and all the variables
y^2-1y+1/2=0
We multiply all the terms by the denominator
y^2*2-1y*2+1=0
Wy multiply elements
2y^2-2y+1=0
a = 2; b = -2; c = +1;
Δ = b2-4ac
Δ = -22-4·2·1
Δ = -4
Delta is less than zero, so there is no solution for the equation
