y^2=460

Solution for y^2=460 equation:

y^2=460

We move all terms to the left:

y^2-(460)=0

a = 1; b = 0; c = -460;
Δ = b2-4ac
Δ = 02-4·1·(-460)
Δ = 1840
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:

$\sqrt{\Delta}=\sqrt{1840}=\sqrt{16*115}=\sqrt{16}*\sqrt{115}=4\sqrt{115}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{115}}{2*1}=\frac{0-4\sqrt{115}}{2}
=-\frac{4\sqrt{115}}{2}
=-2\sqrt{115}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{115}}{2*1}=\frac{0+4\sqrt{115}}{2}
=\frac{4\sqrt{115}}{2}
=2\sqrt{115}
