Special FactorizationsFour special factorizations occur so often that they arelisted here for future reference.} } SPECIAL FACTORIZATIONS x x x x A polynomial that cannot be factored is called a primepolynomial. EXAMPLE Factor each of the following. (a) 64p (b) x (c) x (d) 9y (e) y (f ) m (g) 8k CAUTION In factoring, always look for a common factor first. Since 36x 36x It would be incomplete to factor it as 36x since each factor can be factored still further. To factormeans to factor completely, so that each polynomial factor isprime. |
