6y^2-31y+1=0
a = 6; b = -31; c = +1;
Δ = b2-4ac
Δ = -312-4·6·1
Δ = 937
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-31)-\sqrt{937}}{2*6}=\frac{31-\sqrt{937}}{12} $$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-31)+\sqrt{937}}{2*6}=\frac{31+\sqrt{937}}{12} $
