Find the zero of polynomial 2x2
-3x-2.

2. Find the remainder when4x3
-5x2
+3x+12 is divided by x-1.

3. By using factor theorem, factorise x2
+x-6

4. Write the following in expanded form ( i) (-2x+3y+4z)2
(ii) (2a- 3b)3

5. Factorise : - 3-12(a-b)2

6. Factorise :- 27x3

+ y3
+ z3
-9xyz

7. If (x-y) = 4 and xy=21 , then find the value of x3
– y
3

.
8. If a+b+c = 9 and ab+bc+ca =26, then find the value of a3
+b3
+ c3
-3abc .

9. By using proper identity,factorise (i) 49x2
+70 xy +25y2
(ii) 4y2
- 4y + 1 . plz its very urgent for me plzz try and give me the answer as soon as possible
