Here are the key steps to factoring when a ≠ 1: 1. Check for GCF. If there is a GCF, factor it out. 2. If no GCF, find two numbers whose product is ac and sum is b. These will be the coefficients of the factors. 3. Split the middle term into two terms using the factors. 4. Factor using the box method, finding the GCF of each row and column. Some examples: 2x2 + 11x + 5 ac = 10, factors are 2, 5 (2x + 1)(x + 5) 3x2 - 5x - 2 ac = -
