What do you think it is?

OpenStudy (anonymous):

c

OpenStudy (anonymous):

am i right

OpenStudy (anonymous):

i am pretty sure c is correct but let me check 1 last time

OpenStudy (anonymous):

what is the x at the bottom of the problem

OpenStudy (anonymous):

idk lol

OpenStudy (welshfella):

Note: as x approaches 1 the denominator approaches zero

OpenStudy (welshfella):

you can use l'hopitals theorem to do this find the derivative of the numerator and the denominator and plug in x = 1

OpenStudy (welshfella):

are you familiar with this?

OpenStudy (anonymous):

\[\frac{x^3+5 x^2+3 x-9}{x-1}=x^2+6 x+9 \]When x = 0, x^2+6 x+9=9

OpenStudy (anonymous):

omg to many people helping lol this is consufing

OpenStudy (welshfella):

c is not right

OpenStudy (anonymous):

ok then what is

OpenStudy (welshfella):

have you done l'hopitals rule in calculus?

OpenStudy (anonymous):

i have not

OpenStudy (welshfella):

oh well i can't think of any other way to do this. There probably is though...

OpenStudy (anonymous):

man i just need to answer this question is there aother way to help with this

OpenStudy (welshfella):

oh ok if we factor the numerators we get (x - 1)(x^2 + 6x + 9) ------------------ (x - 1) so the x-1 cancels out to give x^2 + 6x + 9

OpenStudy (welshfella):

now plug in x = 1 into x^2 + 6x + 9 and see what you get

OpenStudy (anonymous):

i got 16

OpenStudy (welshfella):

thats the answer

OpenStudy (welshfella):

ok?
