By Jerry Pallotta

Best-selling writer Jerry Pallotta and illustrator Rob Bolster weigh in with their 8th yummy 32-page Hershey's math book--this time, utilizing different Hershey's chocolates to give an explanation for weights and measures

How lengthy is a foot? what's the metric approach? What weighs extra, a ton of feathers or a ton of Hershey's sweet? writer and educator Jerry Pallotta solutions those and many different questions as in simple terms he can--using Hershey's Kisses, Twizzlers goodies, Hershey's chocolate bars, and extra to coach weights and measurements. Rob Bolster's comical clowns show the concepts.

This is the 8th booklet within the sequence through Pallotta and Bolster, who've taught children counting by way of fives, addition, subtraction, fractions, multiplication, percents, shapes, and patterns.

This technique, called factoring by grouping, is illustrated in the next example. 38 CHAPTER 1 FUNDAMENTAL CONCEPTS OF ALGEBRA EXAMPLE 10 Factoring by grouping Factor: (a) 4ac ϩ 2bc Ϫ 2ad Ϫ bd (b) 3x 3 ϩ 2x 2 Ϫ 12x Ϫ 8 (c) x 2 Ϫ 16y 2 ϩ 10x ϩ 25 SOLUTION (a) We group the first two terms and the last two terms and then proceed as follows: 4ac ϩ 2bc Ϫ 2ad Ϫ bd ϭ ͑4ac ϩ 2bc͒ Ϫ ͑2ad ϩ bd͒ ϭ 2c͑2a ϩ b͒ Ϫ d͑2a ϩ b͒ At this stage we have not factored the given expression because the right-hand side has the form 2ck Ϫ dk with k ϭ 2a ϩ b.

We can extend this formula to m Յ 0 or n Յ 0 by using the definitions of the zero exponent and negative exponents.

For example, x 2 Ϫ 2 is irreducible over the rational numbers, since it cannot be expressed as a product of two polynomials of positive degree that have rational coefficients. However, x 2 Ϫ 2 is not irreducible over the real numbers, since we can write x 2 Ϫ 2 ϭ ͑ x ϩ 22͒͑ x Ϫ 22͒. 4, not over the complex numbers. Every polynomial ax ϩ b of degree 1 is irreducible. Before we factor a polynomial, we must specify the number system (or set) from which the coefficients of the factors are to be chosen.
