Question

Factorise a-b-a2+b2
whoever answers me be the branliest​

Answer 1

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

Answer:

a - b - a2 + b2

a - b - a2 + b2= (a-b) - (a2 - b2)

a - b - a2 + b2= (a-b) - (a2 - b2)= (a - b) - (a + b)(a - b)
