Question

b=3,c=4, centre at origin;foci on the x axis​

Answer 1

Answer:

$we \: know \: in \: ellipse \\ c = \sqrt{ {a}^{2} - {b}^{2} } \\ so \: 4 = \sqrt{ {a}^{2} - {3}^{2} } \\ 16 = {a}^{2} - 9 \\ {a}^{2} = 25 \\ \\ so \: equation \: of \: ellipse \: is \: \\ \frac{ {x}^{2} }{ {a}^{2} } + \frac{ {y}^{2} }{ {b}^{2} } = 1 \\ \frac{ {x}^{2} }{25} + \frac{ {y}^{2} }{16} = 1$

Answer 2

Answer:

the above answer is correct
