Identify and find the properties of the conic section $$$9 x^{2} - 35 = 14$$$.
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, $$$A = 9$$$, $$$B = 0$$$, $$$C = 0$$$, $$$D = 0$$$, $$$E = 0$$$, $$$F = -49$$$.
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
$$$9 x^{2} - 35 = 14$$$A represents a pair of the lines $$$x = - \frac{7}{3}$$$, $$$x = \frac{7}{3}$$$A.
General form: $$$9 x^{2} - 49 = 0$$$A.
Factored form: $$$\left(3 x - 7\right) \left(3 x + 7\right) = 0$$$A.
