      Dear Organic Chemistry Teacher and other people out there I think the third example is very wrong! If you see the negative sign was on the y side (right side) so it would be wrong to assume that the graph is -x^2=y. Also when solving for the foci shouldn't it have been 7/2 because 3-(-1/2) = 7/2 but the video showed 5/2 but I can also see that if the foci is 7/2 the whole graph would be very wrong. Let me also add that the solution for the directrix is also wrong! 3+(-1/2)=5/2 not 7/2 Please help me!!

      How did you do it? Where did you get the ±5 before the 189??
      mine was x= -1±3√21/5 as 189 can be simplified as √9*21 = 3√ 21 and √25 = 5

    • @carloszestyboy2901
      @carloszestyboy2901 3 месяца назад

      @@stupefyore your answer is the correct one I believe (its what i got anyways). √189 breaks down into √9 and √21, which then breaks down further into 3√21. √25 is of course 5 which goes underneath.

    • @lozzizz
      @lozzizz 3 месяца назад +3

      actually it's negative 5, not positive 5 in the numerator x= (-5±√189)/5
      because you minus 1 from each side in x+1 = ± √(189/25)
      @cllsl_dunce the -5± before the 189 is the -1 put into the numerator of the /5 fraction (you're correct)
      x= -1 ± 3√21/5
      x= (-5 ± 3√21) /5

      Dear Organic Chemistry Teacher and other people out there I think the third example is very wrong! If you see the negative sign was on the y side (right side) so it would be wrong to assume that the graph is -x^2=y. Also when solving for the foci shouldn't it have been 7/2 because 3-(-1/2) = 7/2 but the video showed 5/2 but I can also see that if the foci is 7/2 the whole graph would be very wrong. Let me also add that the solution for the directrix is also wrong! 3+(-1/2)=5/2 not 7/2 Please help me!!

    • @MariaM-wq3vn
      @MariaM-wq3vn 4 года назад

      @@jerasong2196 As I am reading the textbook and watching this video, for the directrix we use -p. In this case it is y=k-p=3-(-1/2). For the foci we use +p in this case it is (h,k+p)=(-1,3+(-1/2)). If you plot the original equation in a graphing calculator you will get the same graph from the video. If you try that -p and +p in the previous parabola examples you will get the same results from the video.

      @jerasong2196 4 года назад

      @@MariaM-wq3vn If it's alright with you may I ask if either the parabola faces up or down is the fornula for foci always (h,k+p) and for directrix is k-p? Then if the parabola faces right or left is the formula for foci always (h+p,k) and for directrix is h-p? I really appreciate if you could reply bro because this is the conclusion I came up with but I'm not sure if it's correct. Thanks! :>

    I've had a class on conics, they did a bad job at explaining why the formula works. I had a hard time trying to determine what all the variable meant. But this cleared up so much that I can't believe I had a hard time understanding it before.
