    If \[p(x)\] is a polynomial of at least degree one and \[p(k)=0,\]then k is known as:

    A) value of \[p(x)\]  

    B) zero of \[p(x)\]

    C) constant term of \[p(x)\]

    D) None of these

    Correct Answer: B

    Solution :

    [b] Zero of \[p(x)\]
    Let    \[p(x)=ax+b\]
    Put       \[x=k\]
                \[p(k)=ak+b=0\]
    \[\therefore \]  k is zero of \[p(x)\].
