Ellipse

Ellipse is expressed by equation 9x2 + 25y2 - 54x - 100y - 44 = 0. Find the length of primary and secondary axes, eccentricity, and coordinates of the center of the ellipse.

Correct answer:

o1 =  10
o2 =  6
x0 =  3
y0 =  2
e =  4

Step-by-step explanation:

(xx0a)2+(yy0b)2=1 (9x254x)+(25y2100y)=44 9 (x26x)+25(y24y)=44  x26x+9=(x3)2 y24y+4=(y2)2  9 (x26x+9)+25(y24y+4)=44+9 9+4 25  9 (x3)2+25 (y2)2=225 9225 (x3)2+25225 (y2)2=1  a=2259=5 b=22525=3  o1=2 a=2 5=10
o2=2 b=2 3=6
x0=3=3
y0=2=2
e=a2b2=5232=4
