My problems will come from page 345 problem 80 and 106, and page 363 problem 68 according to the 3 rd letter of my last name. In this discussion I will be using the ac method to factor each polynomial. this the formula for that which is ax^2 + bx +c Problem 80 is w^2 + 30w + 81 For the ac method we need to find two numbers that have the product of ac , and a sum equal to b . We start this process by finding the factor pair of 81 that adds up to 30. We could find the prime factor which is where we could find the factor to the lowest level (1x81), (3x27), (9x9) so it will be 3x27. w^2 + 30w + 81 w^2 + 27w + 3w + 81 (w+3)w+(w+3)27 we will use grouping to factor out w +3 (w+3)(w+27) Once we have factored out (w + 3) this is what we have left and this is the answer. Problem 106 ac + xc +aw ^2 +xw^2 We will be grouping the terms together so that we can find
