5y^2-22y+21=0
a = 5; b = -22; c = +21;
Δ = b2-4ac
Δ = -222-4·5·21
Δ = 64
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{64}=8$$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-22)-8}{2*5}=\frac{14}{10} =1+2/5 $$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-22)+8}{2*5}=\frac{30}{10} =3 $
