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.

Three things to check in conic sections: degree of x and y, coefficient and signs of coefficients.
.
.
.
Circle : Degree 2 for both x and y, equal coefficients, both positive.
.
Parabola : Degree 2 for y and degree 1 for y, coefficients not important.
.
Ellipse: Degree 2 for both x and y, unequal coefficients, both positive.
.
Hyperbola : Degree 2 for both x and y, coefficients not important, one positive, one negative.

x and y degree 2.
Coefficients:One positive, one negative.
Hyperbola.

You could also divide by 144 and look for general forms of conic sections.

The general form for a hyperbola is,

In your case,
