Factorise the following polynomials: 18p^2q^2 – 24pq^2 + 30p^2q

(i) 18p²q² – 24pq² + 30p²q
(ii) 27a³b³ – 18a²b³ + 75a³b²

Solution:

(i) 15a (2p – 3p) – 106 (2p – 3q)
(ii) 3a (x² + y²) + 6b (x² + y²)

Solution:

(i) 6(x + 2y)³ + 8(x + 2y)²
(ii) 14(a – 3b)³ – 21p(a – 3b)

Solution:

10a (2p + q)³ – 15b (2p + q)² + 35(2p + q)
