(i) 5x2 + 17xy – 12y2

(ii) x2y2 – 8xy – 48

Answer :

(i) 5x2 + 17xy – 12y2

5x2 + 20xy – 3xy – 12y2

Take out common in all terms we get,

5x(x + 4y) – 3y(x + 4y)

(x + 4y) (5x – 3y)

(ii) x2y2 – 8xy – 48

x2y2 – 8xy – 48

x2y2 – 12xy + 4xy – 48

Take out common in all terms we get,

xy(xy – 12) + 4(xy – 12)

(xy – 12) (xy + 4)
