25x cube y -121 xy cube
=xy(25xsq -121ysq)
= xy[ ( 5x)sq -(11y)sq]
= xy(5x+11y)(5x-11y)Ans
=xy(25xsq -121ysq)
= xy[ ( 5x)sq -(11y)sq]
= xy(5x+11y)(5x-11y)Ans

25x^3y-121xy^3
= xy(25x^2. -121y^2)
=. xy {(5x)^2. - (11y)^2}
= xy(5x+11y)(5x-11y)
= xy(25x^2. -121y^2)
=. xy {(5x)^2. - (11y)^2}
= xy(5x+11y)(5x-11y)
