-5y^2+22y-8=0
a = -5; b = 22; c = -8;
Δ = b2-4ac
Δ = 222-4·(-5)·(-8)
Δ = 324
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}$$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{324}=18$$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(22)-18}{2*-5}=\frac{-40}{-10} =+4 $$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(22)+18}{2*-5}=\frac{-4}{-10} =2/5 $
