for WHAT?!?!?!?!
OpenStudy (kaylaprincess):
It's either y = 0 or, y = x - 2
OpenStudy (kaylaprincess):
not sure...
OpenStudy (anonymous):
:'(
i don't know this type of math.
OpenStudy (kaylaprincess):
no worries.

did you do polynomial/synthetic division? look at the remainder
OpenStudy (steve816):
It's y = x-6
OpenStudy (steve816):
oblique asymptotes can't be horizontal.
OpenStudy (kaylaprincess):
didn't think I could \[\frac{ (x-2)(x-2) }{ x }\]
OpenStudy (inkyvoyd):
you factored that miserably wrong.

jeeeezzz lol
OpenStudy (inkyvoyd):
x^2-4x+8 doesn't have rational roots.
OpenStudy (kaylaprincess):
i know i know cause x + 2 is stuck together lol
OpenStudy (inkyvoyd):
It does have complex roots, but that is beside the point. The proper way to do thsi problem is to do polynomial or synthetic division.
OpenStudy (inkyvoyd):
what is x^2-4x+8 divided by x+2?

synthetic <3
OpenStudy (kaylaprincess):
lemme do it right now :-)
OpenStudy (steve816):
You have to use synthetic division. Khan academy has a great video on it.
OpenStudy (kaylaprincess):
im so dumb WHY did I not see to use synthetic division lolllll @ me this is embarrassing
OpenStudy (inkyvoyd):
after doing the division you should come to the same conclusion as steve

thank you everyone lol
OpenStudy (inkyvoyd):
and I was wrong before, it is not the remainder you are interested in. it is the quotient.
OpenStudy (kaylaprincess):
correctttt didnt catch that
OpenStudy (inkyvoyd):
because for any remainder 1/(x^2-a) as x approaches infinity, the expression becomes zero and you are left with just the quotient.
OpenStudy (kaylaprincess):
isnt this so fun

or really 1/(polynomial in x)
OpenStudy (inkyvoyd):
it is great review for me, surely :)
OpenStudy (kaylaprincess):
got x -6! Thankkk you
OpenStudy (inkyvoyd):
:)
