  1. You will need to know "algebraic long division"
    It is very difficult to show it on this text format, but this webpage has a couple of good examples

    http://www.sosmath.com/algebra/factor/fac01/fac01.html

    Try your questions by following the above method

    If the coefficient of the variable in your divisor is 1 , like in your last 4 problems, "synthetic division" can be used.
    Khan has an excellent video showing the steps of synthetic division
    http://www.sosmath.com/algebra/factor/fac01/fac01.html

    I suggest doing the last 4 using this method and seeing how much faster the method is.
    You should of course get the same answers
