vertices (x^2}{81}+\frac{y^2)/9 =1

vertices

\frac{x ^{2}}{81} + \frac{y ^{2}}{9} = 1

(9, 0), (- 9, 0)

Solution steps

(h + a, k), (h - a, k)

Calculate ellipse properties

\frac{x ^{2}}{81} + \frac{y ^{2}}{9} = 1 :

Ellipse with center

(h, k) = (0, 0), a = 9, b = 3

(0 + 9, 0), (0 - 9, 0)

Refine

(9, 0), (- 9, 0)

\frac{( x - 2 ) ^{2}}{9} + \frac{( y - 3 ) ^{2}}{49} = 1

9 x^{2} + 81 y^{2} - 729 = 0

16 x^{2} + 4 y^{2} = 64

y^{2} = 1 - 2 x^{2}

\frac{( x - 3 ) ^{2}}{4} + \frac{( y - 4 ) ^{2}}{25} = 1
