Question

How do you factorise this
pq + p - 3q - 3
​

Answer 1

(p - 3)(q + 1)

Explanation:

Rearrange the terms in the expression as

pq - 3q + p - 3 ( factor the first/second and third/fourth terms )

= q(p - 3) + 1(p - 3) ← factor out (p - 3) from each term

= (p - 3)(q + 1) ← in factored form
