Question

How do you combine `6/(w(w-2))+3/w`?

Answer 1

See below.

Explanation:

We have to find the least common factor in the denominator. Since they both have a `w` term, but the second fraction lacks the `w-2` term, we multiply the second fraction by `(w-2)/(w-2)`.

`6/(w(w-2))+3/w\cdot(w-2)/(w-2)=(6+3w-6)/(w(w-2))=(3w)/(w(w-2))=3/(w-2)`
