Wy multiply elements

16y^2-1520y+211=0

a = 16; b = -1520; c = +211;
Δ = b2-4ac
Δ = -15202-4·16·211
Δ = 2296896
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:

$\sqrt{\Delta}=\sqrt{2296896}=\sqrt{64*35889}=\sqrt{64}*\sqrt{35889}=8\sqrt{35889}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-1520)-8\sqrt{35889}}{2*16}=\frac{1520-8\sqrt{35889}}{32}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1520)+8\sqrt{35889}}{2*16}=\frac{1520+8\sqrt{35889}}{32}
