15x^2+12y^2+30x-24y=150

15 x^{2} + 12 y^{2} + 30 x - 24 y = 150

(h, k) = (- 1, 1), a = \frac{59}{5}, b = \frac{59}{2}

Solution steps

15 x^{2} + 12 y^{2} + 30 x - 24 y = 150

Rewrite

15 x^{2} + 12 y^{2} + 30 x - 24 y = 150

in the form of the standard ellipse equation

\frac{( x - ( - 1 ) ) ^{2}}{( \frac{59}{5} ) ^{2}} + \frac{( y - 1 ) ^{2}}{( \frac{59}{2} ) ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (- 1, 1), a = \frac{59}{5}, b = \frac{59}{2}

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (- 1, 1), b = \frac{59}{2}, a = \frac{59}{5}
