1. The problem statement, all variables and given/known data I have been sitting here for the last hour trying to figure it out but I can't seem to be able to find what I'm doing wrong. I need to expand an equation. 2. Relevant equations a2 - a - 3 3. The attempt at a solution a2 - 1a - 3 The product is -3 and the sum -1. -3 * 1 = -3 -1 * 3 = -3. Both products are -3. I can't seem to be able to find anything though of which the sum is also -1. My sums are always either -2 or 2.
