2y^2+47y=0
a = 2; b = 47; c = 0;
Δ = b2-4ac
Δ = 472-4·2·0
Δ = 2209
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2209}=47$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(47)-47}{2*2}=\frac{-94}{4} =-23+1/2 $
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(47)+47}{2*2}=\frac{0}{4} =0 $
