So I completely forgot to blog an i have 2 minutes so here's my attempt at half credit:
This week I remember learning about a bunch of stuff i don't completely understand but i do understand how to solve this kind:
x^2 + 2x + 4/ x^2 - 4
you just factor the top and bottom
(x+2) (x+2)/ x+2)(x-2)
-cancel
x+2/x-2 x=2 is vertical asymtote, x=-2 is a removable.
Out of time.....
