64-36y2=0

Solution for 64-36y2=0 equation:

64-36y^2=0

a = -36; b = 0; c = +64;
Δ = b2-4ac
Δ = 02-4·(-36)·64
Δ = 9216
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{9216}=96$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-96}{2*-36}=\frac{-96}{-72}
=1+1/3
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+96}{2*-36}=\frac{96}{-72}
=-1+1/3
