Question
In Problems $23-30$, use the given zero to find the remaining zeros of each function.$$h(x)=3 x^{4}+5 x^{3}+25 x^{2}+45 x-18 ; \quad \text { zero: } 3 i$$
Step 1
Since the coefficients of the polynomial are real numbers, the complex conjugate of $3i$, which is $-3i$, is also a zero of the polynomial. Show more…
