10y^2+60y+50=0
a = 10; b = 60; c = +50;
Δ = b2-4ac
Δ = 602-4·10·50
Δ = 1600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1600}=40$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(60)-40}{2*10}=\frac{-100}{20} =-5 $
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(60)+40}{2*10}=\frac{-20}{20} =-1 $
