Hi ,
x² y² - 12xy - 45
= x² y² - 15xy + 3 xy - 45
= xy ( xy - 15 ) + 3 ( xy - 15 )
= ( xy - 15 )( xy + 3 )
I hope this helps you.

x2y2-12xy-45=x2y2-15xy+3xy-45
=xy(xy-15)+3(xy-15)
=(xy+3) (xy-15)
x2 y2 stands for x ka square and y ka square
=xy(xy-15)+3(xy-15)
=(xy+3) (xy-15)
x2 y2 stands for x ka square and y ka square
