We often arrange the terms of a polynomial in order of decreasing powers of the variable; thus, we write 2 2 5z 2 2 5z Ϫ 3z7 ϩ 8 Ϫ 25 z 4 ϭ Ϫ3z7 Ϫ 25 z4 ϩ 25 z2 ϩ 8. We may regard a polynomial in x as an algebraic expression obtained by employing a finite number of additions, subtractions, and multiplications involving x. If an algebraic expression contains divisions or roots involving a variable x, then it is not a polynomial in x. 1. In particular, if additions, subtractions, and multiplications are carried out with polynomials, we may simplify the results by using properties of real numbers, as demonstrated in the following examples.

In the next example we illustrate different methods for finding the product of two polynomials. EXAMPLE 3 Multiplying polynomials Find the product: ͑x 2 ϩ 5x Ϫ 4͒͑2x 3 ϩ 3x Ϫ 1͒ SOLUTION Method 1 We begin by using a distributive property, treating the polynomial 2x 3 ϩ 3x Ϫ 1 as a single real number: ͑x 2 ϩ 5x Ϫ 4͒͑2x 3 ϩ 3x Ϫ 1͒ ෇ x 2͑2x 3 ϩ 3x Ϫ 1͒ ϩ 5x͑2x 3 ϩ 3x Ϫ 1͒ Ϫ 4͑2x 3 ϩ 3x Ϫ 1͒ We next use another distributive property three times and simplify the result, obtaining ͑x 2 ϩ 5x Ϫ 4͒͑2x 3 ϩ 3x Ϫ 1͒ ෇ 2x 5 ϩ 3x 3 Ϫ x 2 ϩ 10x 4 ϩ 15x 2 Ϫ 5x Ϫ 8x 3 Ϫ 12x ϩ 4 ෇ 2x 5 ϩ 10x 4 Ϫ 5x 3 ϩ 14x 2 Ϫ 17x ϩ 4.
