Question

3y(x-y)-2x(y-2x)/7x(x-y)-3(x2-y2)​

Answer 1

Step-by-step explanation:

Given

3y(x−y)−2x(y−2x)/7x(x−y)−3(x2−y2)

= 3xy−3y2−2xy+4x2/7x2−7xy−3x2+3y2

= 4x2+xy+3y2/4x2−7xy+3y2

= 4x2+4xy−3xy−3y2/4x2−4xy−3xy+3y2

= 4x(x+y)−3y(x+y)/4x(x−y)−3y(x−y)

= (4x−3y)(x+y)/(4x−3y)(x−y)

= x+y/x−y

Therefore option c is correct.....
