Question

step by step guide I am stuck at the part where you have to divide, I have split them up into 2 and got GCF for p on first term and 6 on second term

Answer 1

We have the next expression:

$pq\text{ - pr + 6q-6r}$

Factorize using factor by grouping.

First, let's find the common terms. The one who is in all terms or majority terms.

In this case, let's use p:

$p(q-r)+6q-6r$

Factorize the common term 6.

$p(q-r)+6(q-r)$

Look at the expressions, both are multiply by (q-r), so we can rewrite the expression like this:

Factorize the common term (q-r)

$(q-r)(p+6)$
