Question

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in standard form.


2, -4, 1+3i

Answer 1

so grab the roots and multiply them to each other
keep in mind that the complex one has a companion, its conjugate, so the roots are \(\bf 2, -4, 1+3i, 1-3i\)

Answer 2

Thank you :)
