    If \[p(x)=ax+b,\]then zero of \[p(x)\] is:

    A) \[a\]

    B)  \[b\]

    C) \[\frac{-a}{b}\]

    D) \[\frac{-b}{a}\]

    Correct Answer: D

    Solution :

    [d] \[p(x)=ax+b\]
    For zeroes of \[p(x),\] \[p(x)=0\]
                            \[ax+b=0\]
    \[\Rightarrow \,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,x=\frac{-b}{a}\]
