Answer: Factor 6a + 15
= 3 (2a + 5)
The expression in the denominator is
![\displaystyle{ x^2-2x-8](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20x%5E2-2x-8)
.
We can use this expression by completing the square, and the difference of squares as follows:
![\displaystyle{ x^2-2x-8=(x^2-2x+1)-9=(x-1)^2-3^2](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20x%5E2-2x-8%3D%28x%5E2-2x%2B1%29-9%3D%28x-1%29%5E2-3%5E2)
![=(x-1-3)(x-1+3)=(x-4)(x+2)](https://tex.z-dn.net/?f=%3D%28x-1-3%29%28x-1%2B3%29%3D%28x-4%29%28x%2B2%29)
.
So, the zeros of the polynomial
![\displaystyle{ P(x)=x^2-2x-8](https://tex.z-dn.net/?f=%5Cdisplaystyle%7B%20P%28x%29%3Dx%5E2-2x-8)
are x=4 and x=-2.
Thus, the asymptotes are the lines x=-2, and x=4.
