  • @Cami1908 yea i was wondering why she said there was no b term because there is. Thanx for clarifing

  • @patelk0524 No, Bxy is different than Bx, BUT the +36x is where the B term is located. B = 36. Not sure why she said there is no "B". also, according to her, if there is no B, then she chose the wrong discriminant situation. Ultimately it is an Ellipse, but her reasoning was incorrect.

  • its Bxy in the equation not just Bx
