    Answer:

    p(2)=2(2)²-3(2)+7k

    2(4)-6+7k

    8-6+7k

    2+7k=0

    k=-2/7

    Answer:

    k = \frac{-2}{7}

    Step-by-step explanation:

    x = 2

    so just replace it in place of x in the whole equation and as 2 is a 0 then the whole of p(x) = 0

    so 2x^{2}-3x+7k = 0

    replacing x by 2

    2(2)^{2}-3(2)+7k =   0

    2(4) – 6 +7k = 0

    2+7k = 0

    7k = -2

    k = \frac{-2}{7}
