You can put this solution on YOUR website!
x%5E3-2x%5E2-x%2B2 When you have four terms that is a hint that you may need to factor by grouping.
%28x%5E3-2x%5E2%29%2B%28-x%2B2%29 Factor the GCF from each parenthesis, that will make them match:
x%5E2%28x-2%29-1%28x-2%29 Factor out the common factor of x-2
%28x-2%29%28x%5E2-1%29 Notice that there is a difference of squares in the 2nd set of parenthesis and factor.
%28x-2%29%28x-1%29%28x%2B1%29
Happy Calculating!!!
