axis 25x^2+4y^2-50x+16y-59=0

axis

25 x^{2} + 4 y^{2} - 50 x + 16 y - 59 = 0

semi - major axis b = 5, semi - minor axis a = 2

Solution steps

25 x^{2} + 4 y^{2} - 50 x + 16 y - 59 = 0

Rewrite

25 x^{2} + 4 y^{2} - 50 x + 16 y - 59 = 0

in the form of the standard ellipse equation

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

Therefore ellipse properties are:

(h, k) = (1, - 2), a = 2, b = 5

b > a

therefore

b

is semi-major axis and

a

is semi-minor axis

Ellipse with center (h, k) = (1, - 2), b = 5, a = 2

\frac{( x - 4 ) ^{2}}{9} + \frac{( y + 2 ) ^{2}}{25} = 1

4 x^{2} + 24 x + 36 + 36 y^{2} - 360 y + 756 = 0

\frac{x ^{2}}{7} + \frac{y ^{2}}{16} = 1

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

4 x^{2} - 16 x + 25 y^{2} + 200 y = - 316
