Question

PLEASE HELP ! What value is a discontinuity of x squared plus 2 x plus 3, all over x squared minus x minus 12?
I know i have to factor the top and bottom but the top can't even be fatored?

Answer 1

my answers are
x = -1

x = -2

x = -3

x = -4


Im guessing its x = -3 since the bottom can be factored to (x-4)(x+3)??

Answer 2

Did you write the numerator out correctly?
x^2 + 2x +3?

Answer 3

Yes thats why im confused

Answer 4

it's impossible to factor

Answer 5

I graphed it, it's saying that only the 2 vertical asymptotes exist, and I suppose you can only choose one answer Shenanigans.

Answer 6

Yeah, I guess the best "guess" would be x = -3, since x=4 is the other asymptote. Broken question dude.

Answer 7

Well if you factor out the denominator one answer x= -3 is possible so I guess Ill go with that one

Answer 8

yes just wantsed a second opinion stupid exam man ): thanks though
