If 2x=3+5i, then what is the value of 2x^(3)+2x^(2)-7x+72 ?

Add the given polynomials.(i) x^(3)-2x^(2)-9;5x^(3)+2x+9

Factorize: (i) 2x^2+5x+3 (ii) 6x^2+5x-6

If (x-3) is the HCF of x^(3) - 2x^(2) +px + 6 and x^(2) - 5x +q, find 6p +5q

If one root of the equation x^(3)+2x^(2)+px+q=0 is i alpha, then prove that equation which has one root 2 is x^(3)-2x^(2)+px-q=0

Check whether q(x) is a multiple of r(x) or not. Where q(x)=2x^(3)-11x^(2)-4x+5, r(x)=2x+1
