In this chapter, we present methods for finding the zeros of f(x) when f(x) is a polynomial. By the time one has finished high school, the methods for finding the roots of first- and second order polynomials have been learned. It is well known that it is not possible to solve for...
When the leading coefficient is 1, the possible rational zeros are the factors of the constant term. How To: Given a polynomial function f(x)f(x), use the Rational Zero Theorem to find rational zeros. Determine all factors of the constant term and all factors of the leading coefficient...
Graphing this function will show how to find the zeroes of the polynomial: Notice that this graph crosses the x-axis at -3, -1, 1, and 3. Therefore the real zeroes of this polynomial are x=±1,±3.What are Complex Zeroes of a Polynomial? Lesson Summary Register to view this lesson...
