Write polynomial equation, in factored form, with root 3(with a multiplicity of 2) and 4i

Root of 3 with a multiplicity of 2  means that  is a factor of the polynomial.and also: complex conjugate root theoremfor a polynomial equation (with real coefficients), if  is a complex root, then must also be a complex root.the conjugate of  is  .therefore,  are also factors.factored form of a possible polynomial equation:

Xis equal to three
