10.3 #35 Discriminant Help
So for number 35 is the discriminant would be found by taking A as the coefficient for x^2 B as the coef for y^2 and C as the coef for x? Does that always stay constant or do you just take the coefficients in order. IE: First coefficient in the order of terms is A second is B etc...

There is actually an equation in teh book.
Ax^2+Bxy+Cy^2+Dx+Ey+F=0, where A,B,C can not equal 0.
a corresponds to X^2, B to xy, and C to y^2, respectively.
B^2-4AC<0 ellipse or circle
B^2-4AC=0 parabola
B^2-4AC>0 hyperbola
