Simplify the following : 5x^(4) - 7x^(2) +8x - 1 +3x^(2) - 9x^(2) + 7 - 3x^(4)+11x - 2 +8x^(2)

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)

If x=2 - 2^((1)/(3)) + 2^((2)/(3)) find the value of x^(3)-6x^(2) + 18x + 18

Find x if [(x^2),(9)] - 3 [(x),(9)] = [(-2),(-18)]

Divide 18x^(4) -15x^(3) + 24x^(2) + 9x " by " 3x
