1.	Factorised form of 23xy – 46x + 54y – 108 is(a) (23x + 54) (y – 2) (b) (23x + 54y) (y – 2)(c) (23xy + 54y) (– 46x – 108) (d) (23x + 54) (y + 2)
Answer» (a) (23x + 54) (y – 2) Factorised form of 23xy – 46x + 54y – 108 is = 23xy – (2 × 23x) + 54y – (2 × 54) Take out the common factors, = 23x (y – 2) + 54 (y – 2) Again take out the common factor, = (y – 2) (23x + 54)

Factorised form of 23xy – 46x + 54y – 108 is(a) (23x + 54) (y – 2) (b) (23x + 54y) (y – 2)(c) (23xy + 54y) (– 46x – 108) (d) (23x + 54) (y + 2)

Answer»

(a) (23x + 54) (y – 2)

Factorised form of 23xy – 46x + 54y – 108 is = 23xy – (2 × 23x) + 54y – (2 × 54)

Take out the common factors,

= 23x (y – 2) + 54 (y – 2)

Again take out the common factor,

= (y – 2) (23x + 54)
