-4 is the slop of the line
Answer:
The least common denominator is (b-8)(b+8)(b-1)
Step-by-step explanation:
We are given expression as
![\frac{b}{b^2-64}-\frac{7b}{b^2+7b-8}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7Bb%5E2-64%7D-%5Cfrac%7B7b%7D%7Bb%5E2%2B7b-8%7D)
Firstly, we will factor both denominators
![b^2-64=b^2-8^2=(b-8)(b+8)](https://tex.z-dn.net/?f=b%5E2-64%3Db%5E2-8%5E2%3D%28b-8%29%28b%2B8%29)
![b^2+7b-8=(b+8)(b-1)](https://tex.z-dn.net/?f=b%5E2%2B7b-8%3D%28b%2B8%29%28b-1%29)
so, we can plug it back
![\frac{b}{(b-8)(b+8)}-\frac{7b}{(b+8)(b-1)}](https://tex.z-dn.net/?f=%5Cfrac%7Bb%7D%7B%28b-8%29%28b%2B8%29%7D-%5Cfrac%7B7b%7D%7B%28b%2B8%29%28b-1%29%7D)
First term denominator is
(b-8)(b+8)
Second term denominator is
(b+8)(b-1)
So,
Least common denominator will be
(b-8)(b+8)(b-1)
So, we get
![LCD=(x-8)(x+8)(x-1)](https://tex.z-dn.net/?f=LCD%3D%28x-8%29%28x%2B8%29%28x-1%29)
