2. Multiplication and Division of Polynomials

4. Binominal * Binominal  Multiply each term of each expression by each term of the other (a + 4) (a – 2) = 1 st Terms + (sum of cross terms) + 2 nd Terms (a + 4) (a – 2) = a(a - 2) + 4(a – 2) = a 2 -2a + 4a – 8 = a 2 + 2a -8  Review Example problems on page 165

5. Multiplication and Division of Polynomials Polynomial / Monomial  Divide each term of the numerator by the monomial in the denominator ( 6X 3 + 12X 2 -3x)/3X = 6X 3 /3X + 12X 2 /3X – 3X/3X = 2X 2 + 4X -1 See Example 8-15 at top of page 167 Polynomial / Binomial  Needs to be accomplished using Long Division methods

6. Multiplication and Division of Polynomials Polynomial / Binomial  Both dividend and divisors are arranged in descending exponent order around the Long Division sign  Example: (a 2 + 3a -54) / (a + 9) Follow the rest of the example that starts at the bottom of page 167.  Do Examples 8-17 thru 8-19 Pages 168 and 169 Do practice problems until its routine
