center 36x^2+9y^2+36y-288=0

center

(0, - 2)

Solution steps

36 x^{2} + 9 y^{2} + 36 y - 288 = 0

Rewrite

36 x^{2} + 9 y^{2} + 36 y - 288 = 0

in the form of the standard ellipse equation

\frac{( x - 0 ) ^{2}}{3 ^{2}} + \frac{( y - ( - 2 ) ) ^{2}}{6 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (0, - 2), a = 3, b = 6

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (0, - 2), b = 6, a = 3

And the center is:

(0, - 2)
