We  have the form

 

(x - h)^2           (y - k)^2

______   +     ________   =  1

  a^2                  b^2

 

a  =(1/2) length  of major axis  =   (1/2)(20)  = 10........a^2  = 100

b = (1/2) length of  mi,or axis =     (1/2) ( 16)  = 8  .....b^2   =64

(5,3)  =( h, k)

 

So we have

 

(x   -5)^2            (y - 3)^2

_______    +     ________   =  1

   100                     64
