Find the HCF of the polynomials f(x)= 6(x^(3) +3x^(2)) (x^(2)-16) (x^(2) + 9x + 18) and g(x) = 8(x^(4) + 4x^(3)) (x^(2) + 6x + 9)^(2)

Factorise (i) x^(2)+9x+18 (ii) 6x^(2)+7x-3 (iii) 2x^(2)-7x-15 (iv) 84-2r-2r^(2)

If alpha and beta the roots of the equation x^(2) + 9x + 18 = 0 , then the quadratic equation having the roots alpha + beta and alpha - beta is "_____" . Where (alpha gt beta) .

Let f(x) =x^(3) - 6x^2 +9x +18 , then f(x) is strictly decreasing in …………

If A={x:x is a multiple of 3, x lt 12} and B={x: x in N, x^(2)-9x+18=0} then find A-B.

If A={x:x is a multiple of 3, x lt 12} and B={x: x in N, x^(2)-9x+18=0} then find A-B.
