Question

factor out (x-y)(x+y)​

Answer 1

Answer:

We factor this expression by making groups of 2 terms

=

(

x

y

+

x

)

+

(

−

y

−

1

)

Now we take the common factors out from each group

=

x

(

y

+

1

)

−

1

(

y

+

1

)

(

y

+

1

)

is a common factor to each of the terms now:

=

(

y

+

1

)

(

x

−

1

)

(

y

+

1

)

(

x

−

1

)

is the Factorised form of

x

y

+

x

−

y

−

1

Answer 2

Answer:

given :

(x-y)(x+y)

factorising :

(x-y)(1-1)

factor will be X and -Y
