1. For the nondegenerate quadratic equation Ax^2+Bxy+Cy^2+Dx+Ey+F=0, explain what each of the following tells you about the graph of the equation. a. B^2- 4AC=0 b. B^2-4AC>0 c. B^2- 4AC<0 d. B is not equal to 0
a. 2 equal real roots b. 2 different real roots c. 2 complex roots d. 2 roots
also doesn't a. tell you that the equation will be a parabola. b. will be a hyperbola. c. will be an ellipse/circle. and d. will be either a hyperbola or an ellipse/circle.
yes
it's a quadratic form, so it can be all that, depend on D
these are the coefficients for the general equations of the conics.. they will determine what type of conic you have... a. parabola b. hyperbola c. ellipse
thank you! what about d?
"B" is the coefficent of the xy term. if B is not equal to zero, i think it was just a rotation of those conics... sorry i can't remember...
ok! thank you anyways :)
