Question

2. Factorise: a - b - a2 + b2.​

Answer 1

Answer:

(a−b)[1−(a+b)] Your answer

Step-by-step explanation:

Given polynomial is

a−b−a 2 +b 2

=(a−b)−(a 2 −b 2 )

=(a−b)−(a−b)(a+b)

=(a−b)[1−(a+b)]

Answer 2

Step-by-step explanation:

a-b-a²+b²

=(a-b)-(a²-b²)

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

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