=======================================
C(n, r) = (n!)/(r!*(n-r)!) is the combination formula
C(7, 5) = (7!)/(5!*(7-5)!)
C(7, 5) = (7!)/(5!*2!)
C(7, 5) = (7*6*5!)/(5!*2!)
C(7, 5) = (7*6)/(2!) ..... note the "5!" terms divided and canceled
C(7, 5) = (7*6)/(2*1)
C(7, 5) = 42/2
C(7, 5) = 21
Answer:
(p - 3)(q + 1)
Step-by-step 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
