Today we learned how to find all roots of a polynomials given a complex root. We reviewed how to find all zeroes given the factored form of an equation. Then we also learned how to write the equations of polynomials in standard form given one complex root. Since we didn't have time to explain all homework problems from yesterday, I included a video explaining the ones you had questions on during class.
