If `(x + 1)(x + 3)` is the HCF of `(x^2+ 3x+2) (x^2+ 2x + a) and (x^2+ 7x + 12) (x^2+7x + b)`, then the value of `6a + 3b =`

If the HCF of polynomials f(x) = (x - 1)(x^(2) + 3x + a) and g(x) = (x + 2) (x^(2) + 2x + b) is (x^(2) + x - 2) , then what are the values of a and b respectively?

If x = 1/(2-sqrt3) then find the value of (x^(3) -2x^2 - 7x +4)

The HCF of the polynomials (2x - 1) (5x^(2) -ax + 3) and (x -3) (2x^(2) + x +b) " is " (2x -1) (x -3) Then the values of a and b respectively are _____

If A = 3x^(2) + 2x - 7 and B = 7x^(3) - 3x + 4 , then find : A - B

If A = 3x^(2) + 2x - 7 and B = 7x^(3) - 3x + 4 , then find : A + B

If (x+5) is the HCF of (x^(2)+2x3b) and (6x^(3)+ax^(2)+3x-10), then a-2b=

a (x) = 3x ^ (6) + 7x ^ (4) + 9x ^ (2) + 2x + 1, b (x) = 2x + 2
