Question

3y(3-y)-2x(y-2x)/7x(x-y)-3(x²-y²)​

Answer 1

x+y

___

x-y

Step-by-step explanation:

Given

7x(x−y)−3(x

2

−y

2

)

3y(x−y)−2x(y−2x)

=

7x

2

−7xy−3x

2

+3y

2

3xy−3y

2

−2xy+4x

2

=

4x

2

−7xy+3y

2

4x

2

+xy+3y

2

=

4x

2

−4xy−3xy+3y

2

4x

2

+4xy−3xy−3y

2

=

4x(x−y)−3y(x−y)

4x(x+y)−3y(x+y)

=

(4x−3y)(x−y)

(4x−3y)(x+y)

=

x−y

x+y
