X*y=1360

Solution for X*y=1360 equation:

X*X=1360

We move all terms to the left:

X*X-(1360)=0

Wy multiply elements

X^2-1360=0

a = 1; b = 0; c = -1360;
Δ = b2-4ac
Δ = 02-4·1·(-1360)
Δ = 5440
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{5440}=\sqrt{64*85}=\sqrt{64}*\sqrt{85}=8\sqrt{85}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-8\sqrt{85}}{2*1}=\frac{0-8\sqrt{85}}{2}
=-\frac{8\sqrt{85}}{2}
=-4\sqrt{85}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+8\sqrt{85}}{2*1}=\frac{0+8\sqrt{85}}{2}
=\frac{8\sqrt{85}}{2}
=4\sqrt{85}
