9x^2+25y^2-900=0

9 x^{2} + 25 y^{2} - 900 = 0

(h, k) = (0, 0), a = 10, b = 6

Solution steps

9 x^{2} + 25 y^{2} - 900 = 0

Rewrite

9 x^{2} + 25 y^{2} - 900 = 0

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{1 0 ^{2}} + \frac{( y - 0 ) ^{2}}{6 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, 0), a = 10, b = 6

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, 0), a = 10, b = 6

\frac{x ^{2}}{36} + \frac{( y + 1 ) ^{2}}{25} = 1

25 (x - 1)^{2} + (y - 1)^{2} = 25

25 x^{2} + 16 y^{2} + 100 x + 32 y - 284 = 0

4 X^{2} + 8 Y^{2} - 24 X + 32 Y - 12 = 0

\frac{( x + 2 ) ^{2}}{4} + \frac{( y - 4 ) ^{2}}{20} = 1
