@jim_thompson5910
jimthompson5910 (jim_thompson5910):
set the denominator x^2 - 4 equal to 0 and solve for x
OpenStudy (iwanttogotostanford):
i don't know how to do that:-(
jimthompson5910 (jim_thompson5910):
hint: x^2 - 4 factors to (x-2)(x+2)
jimthompson5910 (jim_thompson5910):
(x-2)(x+2) = 0 breaks down into
x-2 = 0
OR
x+2 = 0
solve each for x

can you do this one like the others before, I'm not being lazy but really that helps me learn the best when i see the whole process as a whole first
jimthompson5910 (jim_thompson5910):
you should give it a shot
jimthompson5910 (jim_thompson5910):
it's ok to get it wrong
OpenStudy (iwanttogotostanford):
ok hold on ill try
OpenStudy (iwanttogotostanford):
so x=2 andx=-2

Here's a similar example
Let's say the denominator was x^2 - 9. Set it equal to 0 and solve for x
x^2 - 9 = 0
(x-3)(x+3) = 0
x-3 = 0 or x+3 = 0
x = 3 or x = -3
So the vertical asymptotes in this example are x = 3 or x = -3. This is not the answer to your question
jimthompson5910 (jim_thompson5910):
`so x=2 andx=-2`
yes those are the correct answers to your problem
