Practice and Problem-Solving (LMS graded)
Find all complex zeros of the given polynomial function, and write the polynomial in completely factored form.
f(x)=2x³ +7
+7x²- - 6x-21
Find the complex zeros of f. Repeat any zeros if their multiplicity is greater than 1.
X=
(Simplify your answer. Use a comma to separate answers as needed. Express complex numbers in terms of i. Type an exact answer, using radicals as neede
in the expression.)
