8y^2=4800
We move all terms to the left:
8y^2-(4800)=0
a = 8; b = 0; c = -4800;
Δ = b2-4ac
Δ = 02-4·8·(-4800)
Δ = 153600
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{153600}=\sqrt{25600*6}=\sqrt{25600}*\sqrt{6}=160\sqrt{6}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-160\sqrt{6}}{2*8}=\frac{0-160\sqrt{6}}{16} =-\frac{160\sqrt{6}}{16} =-10\sqrt{6} $
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+160\sqrt{6}}{2*8}=\frac{0+160\sqrt{6}}{16} =\frac{160\sqrt{6}}{16} =10\sqrt{6} $
