  • P = (x^2 - 2x + 1)log(x + 1) = (x - 1)^2log(x + 1)
    = (1/2)(x - 1)log(x + 1)
    Q = (x^2 + 2x + 1)log(x - 1) = (x + 1)^2log(x - 1)
    = (1/2)(x + 1)log(x - 1)
    PQ = (1/2)(x - 1)log(x + 1).(1/2)(x + 1)log(x - 1)
    = (1/4)(x - 1)log(x + 1).(x + 1)log(x - 1)
    = (1/4)(x - 1)log(x - 1)
    = (1/4)(1)
    = 1/4
