4x^2+8y^2-8x+48y+44=0

4 x^{2} + 8 y^{2} - 8 x + 48 y + 44 = 0

(h, k) = (1, - 3), a = 22, b = 2

Solution steps

4 x^{2} + 8 y^{2} - 8 x + 48 y + 44 = 0

Rewrite

4 x^{2} + 8 y^{2} - 8 x + 48 y + 44 = 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (1, - 3), a = 22, b = 2

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (1, - 3), a = 22, b = 2
