Question 1.
Factorise:
(i) 12x + 36
(ii) 22y – 33z
(iii) 14pq + 35pqr
Answer:
(i) 12x + 36
= (2 x 2 x 3)x + 2 x 2 x 3 x 3
= (2 x 2 x 3) [x + 3]
= 12 (x + 3)

(ii) 22y – 33z
= 2 x 11xy – 3 x 11 x z
= 11 (2y – 3z)

(iii) 14pq + 35pqr
= 2 x 7 x p x q + 5 x 7 x p x q x r
= 7pq (2 + 5r)

Question 1.
Divide:
(i) 24xy²z³ by 6yz²
(ii) 63a² b⁴ c⁶ by 7a² b² c³
Answer:
(i) 24xy²z³ by 6yz²

= 2 x 2 x x x y x z = 4xyz

(ii) 63a² b⁴ c⁶ by 7a² b² c³
= 3 x 3 x a^2-2 b^4-22 c^6-3
= 9 x a⁰ x b² x c³
= 9b²c³ (a° = 1)
