**(i) (x – y) ^{2} – 6(x – y) + 5**

**(ii) (2x – y) ^{2} – 11(2x – y) + 28**

**Answer :**

**(i) (x – y)**^{2} – 6(x – y) + 5

^{2}– 6(x – y) + 5

Above terms can be written as,

(x – y)^{2} – 5(x – y) – (x – y) + 5

(x – y) (x – y – 5) – 1(x – y – 5)

Then,

(x – y – 5) (x – y – 1)

**(ii) (2x – y)**^{2} – 11(2x – y) + 28

^{2}– 11(2x – y) + 28

(2x – y)^{2} – 11(2x – y) + 28

Above terms can be written as,

(2x – y)^{2} – 7(2x – y) – 4(2x – y) + 28

(2x – y) (2x – y – 7) – 4(2x – y – 7)

(2x – y – 7) (2x – y – 4)
