Use the given zero to find all the zeros of the function. Function: f(x)=5x^3+6x^2+45x+54 Zero: 3i Since the polynomial has real coefficients, the complex conjugate is also a zero of the function. Therefore, since 3i is a zero, -3i is also a zero of the function. Use synthetic division to divide the polynomial by the two known zeros, starting with 3i. Show Your Work
