(x - 2) respectively . If 2 A – B = 10, find the value of a .

10. Show that (x-1) is a factor of the polynomial p(x) =x 3 + 2x 2 – x – 2 and hence factorise p(x) .

11. Simplify : (√3 + 1)( 1-√12) + 9 /(√3 + √12)

16. Represent √9.3 on the number line .

17. The volume of cuboid is polynomial p(x) = 8 x 3 + 12 x 2 – 2x – 3. Find possible expression for

dimension of the cuboid . Varify the result by taking x = 5 units.

18. If a x = b , b y = c and c z = a , then prove that xyz = 1 .

19. Find the value of 8 x 3 + 27 y 3 if 2x + 3y = 8 and xy = 2 .
