**(i) 5x ^{2} + 17xy – 12y^{2}**

**(ii) x ^{2}y^{2} – 8xy – 48**

**Answer :**

**(i) 5x**^{2} + 17xy – 12y^{2}

^{2}+ 17xy – 12y

^{2}

5x^{2} + 20xy – 3xy – 12y^{2}

Take out common in all terms we get,

5x(x + 4y) – 3y(x + 4y)

(x + 4y) (5x – 3y)

**(ii) x**^{2}y^{2} – 8xy – 48

^{2}y

^{2}– 8xy – 48

x^{2}y^{2} – 8xy – 48

x^{2}y^{2} – 12xy + 4xy – 48

Take out common in all terms we get,

xy(xy – 12) + 4(xy – 12)

(xy – 12) (xy + 4)
