n1=−−4y2−308y+62412−792yn_{1} = - \frac{- \frac{\sqrt{4 y^{2} - 308 y + 6241}}{2} - \frac{79}{2}}{y}
=
4y2−308y+6241+792y\frac{\sqrt{4 y^{2} - 308 y + 6241} + 79}{2 y}
=
-(-39.5 - 39.5*(1 + 0.000640922929017786*y^2 - 0.0493510655343695*y)^0.5)/y

x1=792−4y2−308y+62412x_{1} = \frac{79}{2} - \frac{\sqrt{4 y^{2} - 308 y + 6241}}{2}
=
792−4y2−308y+62412\frac{79}{2} - \frac{\sqrt{4 y^{2} - 308 y + 6241}}{2}
=
39.5 - 39.5*(1 + 0.000640922929017786*y^2 - 0.0493510655343695*y)^0.5
n2=−4y2−308y+62412−792yn_{2} = - \frac{\frac{\sqrt{4 y^{2} - 308 y + 6241}}{2} - \frac{79}{2}}{y}
=
79−4y2−308y+62412y\frac{79 - \sqrt{4 y^{2} - 308 y + 6241}}{2 y}
=
-(-39.5 + 39.5*(1 + 0.000640922929017786*y^2 - 0.0493510655343695*y)^0.5)/y

x2=4y2−308y+62412+792x_{2} = \frac{\sqrt{4 y^{2} - 308 y + 6241}}{2} + \frac{79}{2}
=
4y2−308y+62412+792\frac{\sqrt{4 y^{2} - 308 y + 6241}}{2} + \frac{79}{2}
=
39.5 + 39.5*(1 + 0.000640922929017786*y^2 - 0.0493510655343695*y)^0.5
