(i) 10y(6y + 21) ÷ 5(2y + 7)
(ii) 9x²y²(3z – 24) ÷ 27xy(z – 8)
(iii) (10y + 14) ÷ 2
(iv) (6x – 15) ÷ (2x – 5)
Solution
(i) 10y(6y + 21) ÷ 5(2y + 7)

(ii) 9x²y²(3z – 24) ÷ 27xy(z – 8)

(iii) (10y + 14) ÷ 2

(iv) (6x – 15) ÷ (2x – 5)

Question 4.
Factorize the expressions and divide them as directed
(i) (y² + 7y + 10) ÷ (y + 5)
(ii) (5x² – 25x + 20) ÷ (x – 1)
(iii) 12xy(9x² – 16y²) ÷ 4xy(3x + 4y)
(iv) 4yz (z² + 6z – 16) ÷ 2y (z + 8)
Solution
(i) (y² + 7y + 10) ÷ (y + 5)
y² + 7y + 10

(ii) (5x² – 25x + 20) ÷ (x – 1)
(5x² – 25x + 20)

(iii) 12xy(9x² – 16y²) ÷ 4xy(3x + 4y)
12xy(9x² – 16y²) ÷ 4xy(3x + 4y)

(iv) 4yz (z² + 6z – 16) ÷ 2y (z + 8)
4yz (z² + 6z – 16) ÷ 2y (z + 8)
