    Answer:

    2x ^{3}  - bx ^{2}  - cx - d = 0 \\ value \: of \: d \: is \: product \: of \: the \: roots \: of \: the \: equation \\ d = 49

    Step-by-step explanation:

    sum of roots = -b/a = -(-b)/2 = b/2 = 94

    *b/2 = 94

    b = 188

    *** product of roots=c/a=-d/2=49

    d = -98
