x^2-2x^2-2y^2-12=0

x^{2} - 2 x^{2} - 2 y^{2} - 12 = 0

(h, k) = (0, 0), a = 23, b = 6

Solution steps

x^{2} - 2 x^{2} - 2 y^{2} - 12 = 0

Rewrite

x^{2} - 2 x^{2} - 2 y^{2} - 12 = 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (0, 0), a = 23, b = 6

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (0, 0), a = 23, b = 6
