2y^2-9y-195=0
a = 2; b = -9; c = -195;
Δ = b2-4ac
Δ = -92-4·2·(-195)
Δ = 1641
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{-(-9)-\sqrt{1641}}{2*2}=\frac{9-\sqrt{1641}}{4} $$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-9)+\sqrt{1641}}{2*2}=\frac{9+\sqrt{1641}}{4} $
