Find polynomial equation from roots
How to Solve Polynomial Equations
Check the roots by generating a graph of this equation using your calculator. For other polynomial functions, we will not be able to draw upon our knowledge of factoring quadratic functions to find roots. For example, you may not be able to factor , but can you still find its zeros by graphing it in your calculator? How? What are the roots of ...

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:
