Question

factorise a²-b²+a-b
pls answer quick​

Answer 1

We know the identity a

2

−b

2

=(a+b)(a−b)

Using the above identity, the given expressiona

2

−b

2

−a+b can be factorised as follows:

a

2

−b

2

−a+b=[(a+b)(a−b)]−1(a−b)=(a−b)(a+b−1)

Hence, a

2

−b

2

−a+b=(a−b)(a+b−1)

Hope it helps

Have a great day ahead ❤️

Answer 2

Answer:

(a-b)(a+b)+a-b=(a-b)(a+b+1)
