Answer 1

Answer:

Here's the correct answer

Step-by-step explanation:

This is an example

You can solve like this

Given expression is 4(a+b)

2

−9(a−b)

2

By using identity a

2

−b

2

=(a+b)(a−b)

It can be factorised as 4(a+b)

2

−9(a−b)

2

=[(2(a+b))

2

−(3(a−b))

2

]

=[2(a+b)+3(a−b)][2(a+b)−3(a−b)]

=[2a+2b+3a−3b][2a+2b−3a+3b]

=(5a−b)(5b−a)

Thus factors are 5a−b,5b−a.

Hope you can understand..
