-2Y*6Y-8*6Y=0
Wy multiply elements
-12Y^2-48Y=0
a = -12; b = -48; c = 0;
Δ = b2-4ac
Δ = -482-4·(-12)·0
Δ = 2304
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$Y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$Y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{2304}=48$
$Y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-48)-48}{2*-12}=\frac{0}{-24} =0 $
$Y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-48)+48}{2*-12}=\frac{96}{-24} =-4 $
