Step-by-step explanation:

(i) (5x−2) by (3x+4)

= (5x−2)×(3x+4)

= 5x(3x+4)−2(3x+4)

= 15x2 +20x−6x−8

= 15x2 +I4x−8

(ii) (4P−7) by (2−3p)

= (4p−7)×(2−3p)

= 4p(2−3p)−7(2−3p)

= 8p−12p 2 −14+21p

= 29p−12p2 −14

(iii) (1.5a−2.5b) by (1.5a+2.5b)

= (1.5a−2.5b) (1.5a+2.5b)

= 1.5a(1.5+2.5b)−2.5b (1.5a+2.5b)

= 2.25a2 +3.75ab−3.75a6 −6.25b2

= 2.25a2 −6.25b2
