(i) (p2 + 5p + 4,) (p + 1)

p2 + 5p + 4 = p2 + p + 4p + 4

= p(p + 1) + 4(p + 1)

= (p + 1) (p + 4)

(p2 + 5p + 4) ÷ (p + 1)

= ((p+1)(p+4)) / (p+1) = p + 4

(ii) 15ab(a2 – 7a + 10) ÷ 3b(a – 2)

15ab (a2 – 7a + 10) ÷ 3b (a – 2)

15ab (a2 – 7a + 10) = 15ab (a2 – 5a – 2a + 10)

= 15ab [(a2 – 2a) – (5a -10)]

= 15ab [a(a – 2) – 5(a – 2)]

= 15ab(a – 2)(a – 5)

∴ 15ab (a2 – 7a + 10) ÷ 3b (a – 2)
