  1. I will read that as:

    4/(x^2 - 4x + 1) + 2/(x^2 - 1)

    We usually "solve" equations, but you have no equation.

    Are you simplifying?
    If so, I was expecting the first denominator to factor like the second one, so we can find the LCD.
    The way it stands, the simplification becomes more complicated than the current expression.

    check your typing.
