    Answer:

    \huge\boxed{\bigstar\:\:\:p=\frac{1}{2}\:\:\:\bigstar }

    Step-by-step explanation:

    Given:-

       3 is a root of Quadratic Equation x²-2px-6=0.

    To Find:-

       The Value of p.

    Solution:-

        p(x)=x²-2px-6=0

     Putting ‘x’=3, we get:

    ⇒ p(3)=(3)²-2p(3)-6=0

    ⇒ 9-6-6p=0

    ⇒ 3=6p

    \implies p=\frac{3}{6}

    \implies\boxed{p=\frac{1}{2} }

    ∴ The Value of p satisfying this Quadratic Equation is \huge{\frac{1}{2} }.

    Answer:

    p=1/2

    Step-by-step explanation:

    give x=3 is one root of Q.E

    q(x)=x^2-2px-6

    as x is 3 when

    x^2-2px-6=0

    when substituting

    9-6p-6=0

    3=6p

    p=1/2

    Hope it helps u…
