1. Adding :

3x²y - 4x - 3y

- 4x + 8y - 6xy

9x²y - 3y

_______________

12x²y - 8x + 2y - 6xy

_______________

2. Factorise :

- 3xy + 9y - x² + 3x

= - 3y ( x - 3 ) - x ( x - 3 )

= ( x - 3 )( - 3y - x )

_______________

3. 800 is not a perfect square .

800 = 2 × 2 × 2 × 2 × 2 × 5 × 5

= 2 × ( 2 × 2 × 5 ) × ( 2 × 2 × 5 )

= 2 × 20 × 20

= 2 × (20)²

Thus,

√800 = √[2 × (20)²]

= 20√2
