Given equation of ellipse is:

Rewrite the equation in the form:

Divide both sides by 16 to get:

This is the standard equation of a vertical ellipse.

1) centre C is (5,-3)

2)Lenghth of major axis is 2a =2*4 =8

3) length of minor axis is 2b=2*sqrt(2)

4)Distance of C from loci

c^2=a^2-b^2

=16-2=14

c=3.74
