Unformatted text preview: That will be discussed in a later section where we will use division of polynomials quite often. © 2007 Paul Dawkins 26 http://tutorial.math.lamar.edu/terms.aspx College Algebra Before actually starting this discussion we need to recall the distributive law. This will be used repeatedly in the remainder of this section. Here is the distributive law. a ( b + c ) = ab + ac We will start with adding and subtracting polynomials. This is probably best done with a couple of examples. Example 1 Perform the indicated operation for each of the following. (a) Add 6 x5 - 10 x 2 + x - 45 to 13 x 2 - 9 x + 4 . [Solution] (b) Subtract 5 x3 - 9 x 2 + x - 3 from x 2 + x + 1 . [Solution] Solution (a) Add 6 x5 - 10 x 2 + x - 45 to 13 x 2 - 9 x + 4 . The first thing that we should do is actually write down the operation that we are being asked to do. (6x 5 - 10 x 2 + x - 45 ) + (13x 2 - 9 x + 4 ) In this case the parenthesis are not required since are adding the two polynomials. They are there simply to make clear the operation t...
