    Step-by-step explanation:

    for quadratic polynomial…

    i) product of zero

    alpha ×beta = c/a

    -4 = -( 2k +2) /1

    -4 = – 2k -2

    -2 = -2k

    k =1

    Step-by-step explanation:

    -4 is the zero of the polynomial

    16-(-4)-(2k+2)

    16+4-2k-2

    18-2k=0

    -2k=-18

    k=9
