Question

How do you factor `7p + pq +6pr`?

Answer 1

`7p+pq+6r=color(green)(p(7+q+6r))`

Explanation:

After extracting the common factor of `color(green)(p)` from each term
we are left with three terms: `color(green)(7, q,)` and `color(green)(6r)` which have no common factors and contain different variables so they can not be further reduced.
