Question 162322
Classify the conic section of each equation. 
10. 25x^2 - 9y^2 = 144 
I think this may be a circle? But im not for sure and I would love to see the correct steps to finding the answer, i know to rewrite x as x-0 and y as y-0, and i know that 144 is also 12^2,but im not sure where to begin. Thank you!

If it were a plus sign, it would be an ellipse.  A circle is a special case of the ellipse, and the coefficients of the x^2 and y^2 terms would be the same.

The minus sign makes it a hyperbola.
