The equation x² 2- - y² -5 -1=0 represents an ellipse if

Options

  1. A>5
  2. B< 2
  3. C2 < < 5
  4. D2> >5

Correct answer

B. < 2

Step-by-step solution

We have, aligned x² 2- - y² -5 -1 &=0 x² 2- + y² 5- &=1 aligned It will represent an ellipse, when array ll & 2- >0 and 5- >0 & < 2 and < 5 & < 2 array
