In this week’s discussion, I will be factoring polynomials using the appropriate strategy associated with the assigned problem. Since the third letter of my name is “n,” on pages 345-6 I will be working on problems 80 and 106 and on page 353 I will be working problem 68. Pages 345-6: 80. w 2 + 30w + 81 The given problem. This trinomial is also in the form of a perfect square . Also each term has a GCF of 3. 81 = 27∙3 81 is the product of 27∙3. 30 = 27 + 3 30 is the sum of 27 + 3. (w + 27)(w + 3) This is polynomial is now completely factored. Since all the terms are positive, we know that both of the factors will be positive. 106. ac + xc + aw
