    Another tip is to simplify the polynomial first to save time. For the polynomial you can write (x^2+x+2x+5)/x+1, then split it into two fractions into (x^2+x)/x+1...this simplifies to x+ (2x+5)/x+1

    if you wanted to check the answer on the first problem, all you would have to do is take the remainder of X +1 and multiply it back times X +2 which would give you X +2 times X +1+3 and that will give you the same thing you started out with.
