If a, b are roots of `3x^2- 4x- 2=0`, then value of `3a^2+ 7b-2/b` is equal to (a)`16/3` (b)`34/3` (c)` 17/5` (d)`28/5`

If a, b and c be the roots of 3 x^(3)+8 x+7=0 , then the value of (a+b)^(3)+(b+c)^(3)+(c+a)^(3) is equal to

If x-a is a factor of x^3-3x^2a+2a^2x+b , then the value of b is (a) 0 (b) 2 (c) 1 (d) 3

If x^(2)+3x+3=0 and ax^(2)+bx+1=0 ,a,b in Q have a common root,then value of (3a +b) is equal to : (A) (1)/(3) (B) 1 (C) 2 (D) 4

a^2b^3\ X\ 2a b^2 is equal to: (a) 2a^3b^4 (b) 2a^3b^5 (c) 2a b (d) a^3b^5

If x=(2)/(3) and x=-3 are the roots of the equation ax^(2)+7x+b=0, find the values of a and b.

If x-a is a factor of x^(3)-3x^(2)a+2a^(2)x+b then the value of b is 0(b)2(c)1(d)3

If a : b = 5 : 2 , then ( a - b )/b is equal to : ( A ) 7/2 ( B ) 3/5 ( C ) 3/2 ( D ) 2/3

If ( x- 3 )/5 - 2 = -1 , then x is equal to ( a ) 8 ( b) 3 ( c ) -7 ( d ) 2
