@shredftw Because they're not in the same term, they're separate terms in the same side of the equation, and as such would both be multiplied by 25. Say, for example, I had x^2 + 5x + 25 = y (purely off the top of my head), and I chose to multiply both sides by 3. That would then become 3x^2 + 15x + 75 = 3y.
I'm still watching the video as I'm posting this, so I don't know if I'm wrong yet, but this is the way I understand it. Hope it helps.
at 6:55 ish when he is taking the square root of that equation to find the slop of the asymptotes why does he completely leave you the term 25? shouldn't the equation of the line be y=+/- 5/2x+5? i watched the previous videos and it still doesn't make sense
THANK YOU SO MUCH,my class went over this during a missionary trip i went on and my teacher never taught me how to do it after that and my final next week has a lot of conic sections
Thank you so much. I'm in Duel Enrollment Calculus and are doing a review on hyperbolas. I completely forgot how to complete the square at the beginning of this video and this was EXACTLY what I needed for my test tomorrow.
these all examples of y-intercept. So, the answer to your question is they are not y-intercept! (I haven't watched the whole video, so you might figure out the rest) :)
nice video. i have a test on this tomorrow. this is very helpful with the formulas that I have already memorized. we have to identify the center, transverse axis, vertices, foci, and asymptotes.
You sound like Jerry Seinfeld. You portray his Cheery laid back personality too. I like that!

How come you didnt do what you did in the last video?

at around 5:30 , when he multiplies both sides by 25, why does he also multiply the x^2 / 4 by 25 as well? they are in the same term...
please help explain this to me!!

I'm in year 12 atm and we have done Hyperbol, where the assymptotes are Vertical and horizontal. Like Y=1/X.
I'll have conics next year.

Is (-1,7) and (-1,-3) the vertices or y intercept??

@masterackz at y-intercept, we have its x-coordinate equal to 0.
e.g.
(0,5)
(0,3)
(0,7)
(0,2)
(0,3.5)
these all examples of y-intercept. So, the answer to your question is no!
