 Question 107858This question is from textbook : Please help me. Using the AC method, please show me the steps to solve this problem. 10m^2-23m-12 This question is from textbook Answer by stanbon(57377)   (Show Source): You can put this solution on YOUR website!the problem you have posted cannot be factored using the AC method. ----------------- The following problem can be Using the AC method, please show me the steps to solve this problem. 10m^2-23m+12 AC = 10*12 = 120 B = -23 ------------- Think of two numbers whose product is 120 and whose sum is -23 The numbers are -15 and -8 -------------- Rewrite the problem replacing -23m by -15m-8m: 10m^2-15m-8m+12 Factor the 1st 2 and the last two terms separately: 5m(2m-3)-4(2m-3) Factor again to get the final answer: (2m-3)(5m-4) ================== Cheers, Stan H.
