How do you factorise with letters?e.g : 4p + pq + 5pr
As you can see, p is present in each term. You may factor that out. You want to factor out the most common factor that is seen in each term. p (4 + q + 5r)
4p + pq + 5prAll of them have p as a commonSo, we just take p out to factorizep(4 + q + 5r)
