xy%2B10x-4y-40 Start with the given expression

%28xy%2B10x%29%2B%28-4y-40%29 Group like terms


x%28y%2B10%29-4%28y%2B10%29 Factor out the GCF x out of the first group. Factor out the GCF -4 out of the second group


%28x-4%29%28y%2B10%29 Since we have the common term y%2B10, we can combine like terms

So xy%2B10x-4y-40 factors to %28x-4%29%28y%2B10%29
