When factoring polynomials you have to make sure both the denominator and numerator are both factor out . For example, x^2+2x+1/ (x+1) , the numerator is not factored.After you factor you should have (x+1)(x+1)/(x+1). (x+1) / (x+1) becomes 1 and 1 times (x+1) equals x+1 as your final answer.
nice example. what else could you add to make your first important sentence a little clearer?
