Unformatted text preview: als. If you don’t remember how to add/subtract/multiply polynomials we will give a quick reminder here and then give a more in depth set of examples the next section. Recall that to add/subtract terms with x in them all we need to do is add/subtract the coefficients of the x. For example, 4 x + 9 x = ( 4 + 9 ) x = 13 x 3 x - 11x = ( 3 - 11) x = -8 x Adding/subtracting radicals works in exactly the same manner. For instance, 4 x + 9 x = ( 4 + 9 ) x = 13 x 3 10 5 - 11 10 5 = ( 3 - 11) 10 5 = -8 10 5 We’ve already seen some multiplication of radicals in the last part of the previous example. If we are looking at the product of two radicals with the same index then all we need to do is use the second property of radicals to combine them then simplify. What we need to look at now are problems like the following set of examples. Example 4 Multiply each of the following. (a) x +2 x - 5 [Solution] ( (b) ( 3 (c) ( 5 )( x- y )( )(2 ) x -5 y x +2 5 x -2 ) ) [Solution] [Solution] Solution In all of these problems all we need to do is recall how to FOI...
