2x^2+5x-3

I thought it did not exist but I guess I was wrong. I really want to know how to do it.

OpenStudy (anonymous):

that would be indeterminate, so you may need to factor then eliminate the common ones or you could use l"hospital's rule if you are familiar with it

OpenStudy (anonymous):

(x+3)(2x-1)/(x+3)(x-3)

OpenStudy (anonymous):

good, now eliminate the like terms

OpenStudy (anonymous):

(2x-1)/(x-3)

OpenStudy (anonymous):

now you can plug in the limit value of -3 to x

OpenStudy (anonymous):

7/6

OpenStudy (anonymous):

you got it

OpenStudy (anonymous):

Awesome! I got this wrong on one of the tests I had taken and I wanted to know how to do it. :)

OpenStudy (anonymous):

OpenStudy (anonymous):
