Answer 2

Answer:

(i) x² + xy – x – y

= x (x + y) -1 (x + y)

= (x + y) (x – 1)

(ii) 5xy + 7y – 5y²– 7x

= 5xy – 5y2 + 7y – 7x

= 5y (x – y) -7 (x – y)

= (x – y)(5y – 1)

(iii) a²b – ab² + 3a – 3b

= ab (a – b) + 3 (a – b)

= (a – b) (ab + 3)

(iv) 6xy²– 3xy – 10y + 5

3xy (2y – 1) -5(2y – 1)

= (2y – 1) (3xy – 5)

(v) x² + xy (1 + y) + y³

= x² + xy + xy² + y³

= x(x + y) + y²(x + y)

= (x + y) (x + y2)

(iv) ab²+ (a – 1) b – 1

= ab² + ab – b – 1

= ab (b + 1) -1 (b + 1)

= (b + 1) (ab – 1)
