The equation 16 x^2+y^2+8 x y-74 x-78 y+212=0 represents
Options
- Aa circle
- Ba parabola
- Ca circle
- Dan ellipse
Correct answer
B. a parabola
Step-by-step solution
The given equation is 16 x^2+y^2+8 x y-74 x-78 y+212=0 On comparing with gathered a x^2+b y^2+2 h x y+2 g x+2 f y+c=0 a=16, b=1, h=4, g=-37, f=-39, c=212 Now, a b-h^2=(16)(1)-(4)^2=16-16=0 gathered Thus, the given equation represents a parabola.
