foci 4x^2+9y^2=36

Solution

foci

4 x^{2} + 9 y^{2} = 36

Solution

(5, 0), (- 5, 0)

Solution steps

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

Calculate ellipse properties

4 x^{2} + 9 y^{2} = 36 :

Ellipse with center

(h, k) = (0, 0), a = 3, b = 2

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

Compute

c :

c = 3^{2} - 2^{2} : 5

(0 + 5, 0), (0 - 5, 0)

Refine

(5, 0), (- 5, 0)

Popular Examples

3x^2+2y^2+6x-4y+5=18

3 x^{2} + 2 y^{2} + 6 x - 4 y + 5 = 18

vertices f(x)=x^2+8x+15 vertices

f (x) = x^{2} + 8 x + 15

directrix y^2=-20x directrix

y^{2} = - 20 x

vertices f(x)=-(x^2)/(10)+(9x)/(10)+11/5 vertices

f (x) = - \frac{x ^{2}}{10} + \frac{9 x}{10} + \frac{11}{5}

directrix y^2=32x directrix

y^{2} = 32 x
