foci ((x)^2)/(49)+((y)^2)/(25)=1

foci

\frac{( x ) ^{2}}{49} + \frac{( y ) ^{2}}{25} = 1

(26, 0), (- 26, 0)

Solution steps

(h + c, k), (h - c, k)

Calculate ellipse properties

\frac{x ^{2}}{49} + \frac{y ^{2}}{25} = 1 :

Ellipse with center

(h, k) = (0, 0), a = 7, b = 5

(0 + c, 0), (0 - c, 0)

Compute

c :

c = 7^{2} - 5^{2} : 26

(0 + 26, 0), (0 - 26, 0)

Refine

(26, 0), (- 26, 0)

\frac{( x - 4 ) ^{2}}{9} + \frac{( y - 7 ) ^{2}}{36} = 1

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

x^{2} + 4 y^{2} = 36

81 x^{2} + 9 y^{2} = 9

\frac{x ^{2}}{16} + \frac{( y - 4 ) ^{2}}{1} = 1
