Identify Factors: Identify common factors in pairs of terms.We can group the terms as follows: 14rs−7r + 6s−3.Now, we look for common factors in each group.In the first group 14rs−7r, the common factor is 7r.In the second group 6s−3, the common factor is 3.
Factor Out Common Factors: Factor out the common factors from each group.From the first group, we factor out 7r, getting 7r(2s−1).From the second group, we factor out 3, getting 3(2s−1).Now we have: 7r(2s−1)+3(2s−1).
Factor Out Binomial Factor: Factor out the common binomial factor.We notice that (2s−1) is a common factor in both terms.We factor (2s−1) out of the expression, getting (2s−1)(7r+3).
