Identify and find the properties of the conic section $$$3 x^{2} - 2 \sqrt{3} - 2 \sqrt{2} = 0$$$.
Solution
The general equation of a conic section is $$$A x^{2} + B x y + C y^{2} + D x + E y + F = 0$$$.
In our case, $$$A = 3$$$, $$$B = 0$$$, $$$C = 0$$$, $$$D = 0$$$, $$$E = 0$$$, $$$F = - 2 \left(\sqrt{2} + \sqrt{3}\right)$$$.
The discriminant of the conic section is $$$\Delta = 4 A C F - A E^{2} - B^{2} F + B D E - C D^{2} = 0$$$.
Next, $$$B^{2} - 4 A C = 0$$$.
Since $$$\Delta = 0$$$, this is the degenerated conic section.
Since $$$B^{2} - 4 A C = 0$$$, the equation represents two parallel lines.
Answer
$$$3 x^{2} - 2 \sqrt{3} - 2 \sqrt{2} = 0$$$A represents a pair of the lines $$$x = - \frac{\sqrt{6 \sqrt{2} + 6 \sqrt{3}}}{3}$$$, $$$x = \frac{\sqrt{6 \sqrt{2} + 6 \sqrt{3}}}{3}$$$A.
General form: $$$3 x^{2} - 2 \left(\sqrt{2} + \sqrt{3}\right) = 0$$$A.
Factored form: $$$\left(3 x - \sqrt{6 \sqrt{2} + 6 \sqrt{3}}\right) \left(3 x + \sqrt{6 \sqrt{2} + 6 \sqrt{3}}\right) = 0$$$A.
