Answer 2

Step-by-step explanation:

It is Given That,

$ab( {x}^{2} + {y}^{2} ) - xy( {a}^{2} + {b}^{2} )$

Now Multiply this ,

$ab {x}^{2} + a b{y}^{2} - (xy {a}^{2} + xy {b}^{2} )$

Now,

$ab {x}^{2} - xy {a}^{2} + ab {y}^{2} - xy {b}^{2}$

Taking,

ax and by Common Factor,

$ax(bx - ay) + by(ay - xb)$

Now,

$ax(bx - ay) - by(xb - ay)$

So we Have again Common Factor,

(bx-ay)

Taking ....

$(bx - ay)(ax - by)$

So this is answer....

Hope it Helpsss!!!!
