ANSWER KEY:-
  • 1. Sol-(C) Since x4 - 1 is the factor of polynomial
    x4  - 1=0
    x = 1, -1
    So / vr% putting x = 1 /
    1 + p + q - 1 - 1 -3 = 0
    p + q = 4 - (i)
    again / iqu% putting x = - 1 /
    1 - p + q - 1 + 1 - 3 = 0
    q - p = 2 - (ii)
    adding (i) & (ii) /
    2q = 6, q = 3
    Now / vc p = 1
    Hence / vr% p2 + q2 = 32 +12 = 10
