The easiest type of factoring occurs when the terms have a common factor. Example 4 Factoring Out Common Factors Factor each expression. (a) 3x 2 Ϫ 6x (c) 12x ϩ 42 1x Ϫ 32 Ϫ 51x Ϫ 3 2 Check Your Answer Solution (a) The greatest common factor of the terms 3x 2 and Ϫ6x is 3x, so we have 3x 2 Ϫ 6x ϭ 3x 1x Ϫ 22 Multiplying gives 3x1x Ϫ 2 2 ϭ 3x 2 Ϫ 6x (b) 8x 4y 2 ϩ 6x 3y 3 Ϫ 2xy 4 (b) We note that 8, 6, and Ϫ2 have the greatest common factor 2 x 4, x 3, and x have the greatest common factor x Check Your Answer Multiplying gives 2xy 14x ϩ 3x y Ϫ y 2 ϭ 2 3 2 2 8x 4y 2 ϩ 6x 3y 3 Ϫ 2xy 4 y 2, y 3, and y 4 have the greatest common factor y 2 So the greatest common factor of the three terms in the polynomial is 2xy 2, and we have 8x 4y 2 ϩ 6x 3y 3 Ϫ 2xy 4 ϭ 12xy 2 2 14x 3 2 ϩ 12xy 2 2 13x 2y2 ϩ 12xy 2 2 1Ϫy 2 2 ϭ 2xy 2 14x 3 ϩ 3x 2y Ϫ y 2 2 28 CHAPTER 1 Fundamentals (c) The two terms have the common factor x Ϫ 3.

The intersection of S and T is the set S ʝ T consisting of all elements that are in both S and T. In other words, S ʝ T is the common part of S and T. The empty set, denoted by л, is the set that contains no element. Example 4 Union and Intersection of Sets If S ϭ {1, 2, 3, 4, 5}, T ϭ {4, 5, 6, 7}, and V ϭ {6, 7, 8}, ﬁnd the sets S ʜ T, S ʝ T, and S ʝ V.
