-12y^2+23y=0

a = -12; b = 23; c = 0;
Δ = b2-4ac
Δ = 232-4·(-12)·0
Δ = 529
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{529}=23$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(23)-23}{2*-12}=\frac{-46}{-24}
=1+11/12
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(23)+23}{2*-12}=\frac{0}{-24}
=0
