Question 761182: Let f be a fourth-degree polynomial function with real coefficients. Three of the zeros of f are -1,2, and 3+2i. What is the fourth zero? Explain Answer by josgarithmetic(39618) (Show Source):
You can put this solution on YOUR website! The situation is comparable to a quadratic equation which has two complex zeros. Complex zeros having imaginary components occur in conjugate pairs. The conjugate of 3+2i is 3-2i.
