**Question 1. Work out the following divisions:**

(i) (35x + 28) ÷ (5x + 4)

(ii) 7p^{2}q^{2}(9r – 27) ÷ 63pq(r – 3)

**Answer:**

(i) (35x + 28) ÷ (5x + 4)

(ii) 7p^{2}q^{2}(9r – 27) ÷ 63pq(r – 3)

= p^{2-1} q^{2-1} × 9 = 9pq

**Question 2. Divide as directed:**

(i) 6(2x + 7) (5x – 3) ÷ 3(5x – 3)

(ii) 33pq (p + 3) (2q – 5) ÷ 11p (2q – 5)

**Answer:**

(i) 6(2x + 7) (5x – 3) ÷ 3(5x – 3)

=

= 2(2x + 7)

(ii) 33pq (p + 3) (2q – 5) ÷ 11p (2q – 5)

=

= 3q(p + 3)

**Question 3. Factorise the expression and divide them as directed:**

(i) (7x^{2} – 63x) ÷ 7(x – 3)

(ii) (3p^{2} + 17p + 10) ÷ (p + 5)

(iii) 10xy(14y^{2} + 43y – 21) ÷ 5x(7y – 3)

(iv) 12pqr(6p^{2} – 13pq + 6q^{2}) ÷ 6pq(2p – 3q)

**Answer:**

**(i) (7x ^{2} – 63x) ÷ 7(x – 3)**

**(ii) (3p ^{2} + 17p + 10 ) ÷ (p + 5)**

= (3p^{2} + 17p + 10)/ (p + 5)

**(iii) 10xy(14y ^{2} + 43y – 21) ÷ 5x(7y – 3)**

**(iv) 12pqr(6p ^{2} – 13pq + 6q^{2}) ÷ 6pq(2p – 3q)**
