Question

ab² + (a – 1)b-1 factorise
​

Answer 1

Question;

Factorise the expression;

ab^2 + (a - 1)b - 1.

Solution:-

=> ab^2 + (a - 1)b - 1

=> ab^2 + ab - b - 1

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

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

Hence,

The factorised form of the given polynomial is: (b + 1)(ab - 1).

Answer 2

Answer:

(b+1) (ab-1)

Step-by-step explanation:

ab^2 +ab-b-1

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

(b+1)(ab-1)
