**(i) 2x ^{2} – x – 6**

**(ii) 1 – 18y – 63y ^{2}**

**Answer :**

**(i) 2x**^{2} – x – 6

^{2}– x – 6

2x^{2} – 4x + 3x – 6

Take out common in all terms we get,

2x(x – 2) + 3(x – 2)

(x – 2) (2x + 3)

**(ii) 1 – 18y – 63y**^{2}

^{2}

1 – 18y – 63y^{2}

1 – 21y + 3y – 63y^{2}

Take out common in all terms we get,

1(1 – 21y) + 3y(1 – 21y)

(1 – 21y) (1 + 3y)
