#### (i) 6xy^{2} – 3xy – 10y + 5

#### (ii) 3ax – 6ay – 8by + 4bx

**Answer :**

**(i) 6xy**^{2} – 3xy – 10y + 5

^{2}– 3xy – 10y + 5

Take out common in all terms,

3xy(2y – 1) – 5(2y – 1)

(2y – 1) (3xy – 5)

**(ii) 3ax – 6ay – 8by + 4bx**

3ax – 6ay – 8by + 4bx

Take out common in all terms,

3a(x – 2y) + 4b (x – 2y)

(x – 2y) (3a + 4b)
