Question

3-5x+5y-12(x-y)² ANS:(3+4x-4y)(1-3x+3y)​

Answer 1

Step-by-step explanation:

Consider 3−5x+5y−12(x−y)

2

=3−5(x−y)−12(x−y)

2

Let x−y be a

Therefore,

=3−5a−12a

2

=−12a

2

−5a+3

=−12a 2

−9a+4a+3

=−3a(4a+3)+1(4a+3)

=(4a+3)(1−3a)

Putting the value of a we get,

=[4(x−y)+3][1−3(x−y)]

=(4x−4y+3)(1−3x+3y)
