A-APR.3. Identify zeros of polynomials when suitable factorizations are available, and use the zeros to construct a rough graph of the function defined by the polynomial. I can determine the zeros of a polynomial from its factors. I can describe and sketch the graph of a polynomial given its zeros. Given a list of "zeros", it is possible to find a polynomial function that has these specific zeros. In fact, there are multiple polynomials that will work. In order to determine an exact polynomial, the "zeros" and a point on the polynomial must be provided. Examples: Practice finding polynomial equations in...

The example we used previous has 3 real roots, which means that there are two imaginary roots. So, if we have a polynomial function, say f(x), of degree n, then f(x) = 0 will have n solutions total. Fact: The number of solutions to a polynomial function of degree n, f(x) = 0 will be n. In this section we will explore those imaginary solutions. It explains how to write polynomial equations given the roots which can be real numbers, imaginary numbers, or complex roots. It also explains how to write polynomial functions in factored form and in standard form. This video contains plenty of examples and practice problems.The first step in finding the solutions of (that is, the x-intercepts of, plus any complex-valued roots of) a given polynomial function is to apply the Rational Roots Test to the polynomial's leading coefficient and constant term, in order to get a list of values that might possibly be solutions to the related polynomial equation. The zero of a polynomial is the value of the which polynomial gives zero. Thus, in order to find zeros of the polynomial, we simply equate polynomial to zero and find the possible values of variables. Let P(x) be a given polynomial. To find zeros, set this polynomial equal to zero. i.e. P(x) = 0.Now, this becomes a polynomial equation.
