Finding Rational Zeros – Notes and Examples
Finding Polynomials with Given Zeros. If a complex number is a zero of a polynomial function with real coefficients, then its conjugate, , is also a zero. Example: Find a polynomial function of degree 3, having the zeros 1, and . Solution: The number can be any nonzero number. The simplest function will be obtained if we let Then we have
