# How do you combine #(4-3x)/ (16-x^2) + 3/( x-4)#?

##### 1 Answer

You need to find the lowest common denominator among these two functions. We can try to factor the first function's denominator in order to ease things for us, as shown:

However, the factors

We just need to multiply it by

So, we can rewrite the whole sum as

Now, our lowest common denominator is

Distributing our factors in the denominator, we have the shortest answer as follows:
