Question
Identify the type of curve that each equation represents by evaluating $B^{2}-4 A C$.$$13 x^{2}+10 x y+13 y^{2}+6 x-42 y-27=0$$
Step 1
The equation is given as $13x^{2}+10xy+13y^{2}+6x-42y-27=0$. Here, the coefficient of $x^{2}$ is $A=13$, the coefficient of $xy$ is $B=10$, and the coefficient of $y^{2}$ is $C=13$. Show more…
