Answer:
We say that x=r is a root or zero of a polynomial, P(x) , if P(r)=0 P ( r ) = 0 . In other words, x=r is a root or zero of a polynomial if it is a solution to the equation P(x)=0 P ( x ) = 0 .
How do you find the roots of a polynomial equation?
You can find the roots, or solutions, of the polynomial equation P(x) = 0 by setting each factor equal to 0 and solving for x. Solve the polynomial equation by factoring. Set each factor equal to 0. 2x4 = 0 or (x – 6) = 0 or (x + 1) = 0 Solve for x.
