center 9x^2+16y^2-72x+64y-368=0

center

9 x^{2} + 16 y^{2} - 72 x + 64 y - 368 = 0

(4, - 2)

Solution steps

9 x^{2} + 16 y^{2} - 72 x + 64 y - 368 = 0

Rewrite

9 x^{2} + 16 y^{2} - 72 x + 64 y - 368 = 0

in the form of the standard ellipse equation

\frac{( x - 4 ) ^{2}}{8 ^{2}} + \frac{( y - ( - 2 ) ) ^{2}}{6 ^{2}} = 1

Therefore ellipse properties are:

(h, k) = (4, - 2), a = 8, b = 6

a > b

therefore

a

is semi-major axis and

b

is semi-minor axis

Ellipse with center (h, k) = (4, - 2), a = 8, b = 6

And the center is:

(4, - 2)

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

\frac{( x + 2 ) ^{2}}{4} + \frac{( y - 4 ) ^{2}}{16} = 1

\frac{x ^{2}}{9} + \frac{y ^{2}}{16} > 1

4 x^{2} + 9 y^{2} = 36

25 x^{2} + 9 y^{2} = 225

What is the center 9x^2+16y^2-72x+64y-368=0 ?
The center 9x^2+16y^2-72x+64y-368=0 is (4,-2)
