xa%2Bxb%2B3a%2B3b Start with the given expression


%28xa%2Bxb%29%2B%283a%2B3b%29 Group the terms in two pairs


x%28a%2Bb%29%2B3%28a%2Bb%29 Factor out the GCF x out of the first group. Factor out the GCF 3 out of the second group


%28x%2B3%29%28a%2Bb%29 Since we have the common term a%2Bb, we can combine like terms


So xa%2Bxb%2B3a%2B3b factors to %28x%2B3%29%28a%2Bb%29


In other words, xa%2Bxb%2B3a%2B3b=%28x%2B3%29%28a%2Bb%29
