# How do you multiply #(1/(r-2)) + (1/(r^2-7r+10))=6/(r-2)#?

##### 1 Answer

In order to **sum** (and not multiply) the first two fractions, we must find the lowest common denominator among them. In order to simplify things for us, we can factor the second denominator, finding its roots, as follows:

Using Bhaskara:

Solving:

Rewriting these roots, we can say that

Rewriting your sum, we get

Summing them:

Now, we have the equation

Cross multiplying them, we get

Now, moving
