Solution for 2y2-24y+64=0 equation: 



2y^2-24y+64=0

a = 2; b = -24; c = +64;
Δ = b2-4ac
Δ = -242-4·2·64
Δ = 64
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{64}=8$


$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-24)-8}{2*2}=\frac{16}{4}
=4
$


$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-24)+8}{2*2}=\frac{32}{4}
=8
$
