If p(x) is a polynomial in x, and if k is any real number, then the value obtained by replacing x by k in p(x), is called the value of p(x) at x = k, and is denoted by p(k).
If p(x) is a polynomial in x, and if k is any real number, then the value obtained by
replacing x by k in p(x), is called the value of p(x) at x = k, and is denoted by p(k).
a real number k is said to be a zero of a polynomial p(x), if p(k) = 0.
a real number k is said to be a zero of a polynomial p(x), if p(k) = 0.
