Now try Exercise 41. Scientific Notation HISTORICAL NOTE The French mathematician Nicolas Chuquet (ca. 1500) wrote Triparty en la science des nombres, in which a form of exponent notation was used.

Another way to factor the polynomial in Example 9 is to group the terms as follows. x3 Ϫ 2x2 ϭ͑ x3 Ϫ 3x͒ Ϫ ͑ ϭ x͑ Ϫ 3͒ Ϫ 2͑ ϭ͑ Ϫ 3͒͑x Ϫ 2͒ x2 x 3 Ϫ 2x 2 Ϫ 3x ϩ 6 ϭ ͑x 3 Ϫ 2x 2͒ Ϫ ͑3x Ϫ 6͒ Ϫ 3x ϩ 6 2x2 x2 Solution x2 Ϫ 6͒ Ϫ 3͒ As you can see, you obtain the same result as in Example 9. Group terms. ϭ x 2͑x Ϫ 2͒ Ϫ 3͑x Ϫ 2͒ Factor each group. ϭ ͑x Ϫ 2͒͑x 2 Ϫ 3͒ Distributive Property Now try Exercise 73. Factoring a trinomial can involve quite a bit of trial and error. Some of this trial and error can be lessened by using factoring by grouping.
