Question

If p(x) is a polynomial of at least degree one and p(k) = 0, then k is known as ______.

Options

• value of p(x)

• zero of p(x)

• constant term of p(x)

• none of these

Answer 1

If p(x) is a polynomial of at least degree one and p(k) = 0, then k is known as zero of p(x).

Explanation:

Zero of p(x)
Let p(x) = ax + b

Put x = k

p(k) = ak + b = 0

∴ k is zero of p(x).
