    Answer:

    12

    Step-by-step explanation:

    Given,

    X – 3 is a factor of p(x)

    => x – 3 = 0

    =>. x = 0+3

    =>. x = 3

    Now,

    p(x) = x² + x – k

    => p(3) = (3)² + 3 – k

    => 9 + 3 – k = 0

    =>. 12 – k. = 0

    =>. -k = 0-12

    =>. -k = -12

    since, there is minus on both sides,

    Therefore,

    -k = -12

    = k = 12

    Therefore, the value of k is 12
