      Investigation on the Roots of Polynomials. Let’s review by finding the roots of quadratic functions. Look at the graph of . Use completing the square or the quadratic formula to verify the solutions you found on the graph. Now, we will try to find roots of polynomials of larger degrees. Let’s start with the cubic polynomial .

      A polynomial function has a factor of if and only if . That is, is a factor if and only if c is a zero of P. Solutions = Roots = Zeros = x-Intercepts. When we find the roots of a polynomial equation, we are finding the places where the value of the function is ZERO. If f (x) = 0, then x is a root!!!! Examples:
