Question 1. Work out the following divisions:

(i) (35x + 28) ÷ (5x + 4)
(ii) 7p²q²(9r – 27) ÷ 63pq(r – 3)

Answer:

(i) (35x + 28) ÷ (5x + 4)

(ii) 7p²q²(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) (7x² – 63x) ÷ 7(x – 3)
(ii) (3p² + 17p + 10) ÷ (p + 5)
(iii) 10xy(14y² + 43y – 21) ÷ 5x(7y – 3)
(iv) 12pqr(6p² – 13pq + 6q²) ÷ 6pq(2p – 3q)

Answer:

(i) (7x² – 63x) ÷ 7(x – 3)

(ii) (3p² + 17p + 10 ) ÷ (p + 5)

= (3p² + 17p + 10)/ (p + 5)

(iii) 10xy(14y² + 43y – 21) ÷ 5x(7y – 3)

(iv) 12pqr(6p² – 13pq + 6q²) ÷ 6pq(2p – 3q)
