Notice that the factoring should reveal the same binomial or polynomial factor in all the groups. We obtain (ax + ay) + (bx + by) = a(x + y ) + ...6(z + y). Divide by x + y and we obtain the quotient a + b. Taking the divisor x + y as one factor, and the quotient a + b as the other factor, we have ox + ay + bx + by = (x +y)(a + b). Factor 2 a - 66 - ad + 3bd. Grouping, (2 a - 6 6) - (ad - 3 bd). Factoring each group, 2 (a 3 6) d(a 3 b). The factor a 3 b is seen to occur in both groups. Dividing by a 3 6, we obtain 2 d. Taking the divisor a 3 b as one factor, and the quotient 2 d as an- other factor, we have 2 a - 6 b - ad + 3 bd =(a - 3 6)(2 - d).
