foci (2x^2)/(25)+((y-3)^2)/(49)=1

foci

(0, 3 + \frac{73}{2}), (0, 3 - \frac{73}{2})

Solution steps

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

Calculate ellipse properties

\frac{2 x ^{2}}{25} + \frac{( y - 3 ) ^{2}}{49} = 1 :

Ellipse with center

(h, k) = (0, 3), b = 7, a = \frac{5}{2}

(0, 3 + c), (0, 3 - c)

Compute

c :

c = 7^{2} - (\frac{5}{2})^{2} : \frac{73}{2}

(0, 3 + \frac{73}{2}), (0, 3 - \frac{73}{2})
