Concept:Factor by grouping terms with common factors.Explanation:Group the expression as (15xy−6x)+(5y−2).Take 3x common from the first group: 3x(5y−2).The second group is 1(5y−2).Now (5y−2) is common, so factor it out: (5y−2)(3x+1).Thus the factors are 3x+1 and 5y−2.Answer:Option B: (3x+1) and (5y−2)
