    • How can I find polynomial function with the zeros?

      How To: Given the zeros of a polynomial function f f and a point (c, f (c)) ( c , f ( c)) on the graph of f f, use the Linear Factorization Theorem to find the polynomial function. Use the zeros to construct the linear factors of the polynomial. Multiply the linear factors to expand the polynomial. Substitute (c,f (c)) ( c, f ( c)) into the function to determine the leading coefficient. Simplify.

    • How to find the zeros of a polynomial?

      Process for Finding Rational Zeroes Use the rational root theorem to list all possible rational zeroes of the polynomial P (x) P ( x). Evaluate the polynomial at the numbers from the first step until we find a zero. ... Repeat the process using Q(x) Q ( x) this time instead of P (x) P ( x). This repeating will continue until we reach a second degree polynomial. ...

    • How do I factor and find zeros in polynomials?

      Use factoring to find zeros of polynomial functions Recall that if f is a polynomial function, the values of x for which \displaystyle f\left (x\right)=0 f (x) = 0 are called zeros of f. If the equation of the polynomial function can be factored, we can set each factor equal to zero and solve for the zeros.

    • How would you find the zeros of the function?

      How To: Given a polynomial function f f, use synthetic division to find its zeros. Use the Rational Zero Theorem to list all possible rational zeros of the function. Use synthetic division to evaluate a given possible zero by synthetically dividing the candidate into the polynomial. ... Repeat step two using the quotient found with synthetic division. ... Find the zeros of the quadratic function. ...
