23y^2+43y=0
a = 23; b = 43; c = 0;
Δ = b2-4ac
Δ = 432-4·23·0
Δ = 1849
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{1849}=43$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(43)-43}{2*23}=\frac{-86}{46} =-1+20/23 $
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(43)+43}{2*23}=\frac{0}{46} =0 $
