$$y=\frac{ x-5 }{x ^{2} +4x+3}$$

what do u mean by describe

anonymous · Answer

Factor the denominator:
x^2 + 4x + 3
= x^2 + x + 3x + 3
= x(x + 1) + 3(x + 1)
= (x + 3)(x + 1)
Since the numerator and denominator have no common factors, there are no holes.
To find vertical asymptotes, the denominator must be zero (and the numerator must be non-zero):
(x + 3)(x + 1) = 0
x + 3 = 0 or x + 1 = 0
x = -3 or x = -1
The answer is asymptotes: x = –3, –1 and no holes.

Thank you! @seiga That's what I thought for the asymptotes but I wasn't sure on how to get the holes
