1. The problem statement, all variables and given/known data My friend and I were having trouble with an equation, but I don't have the exact one with me so I will write one that is similar and is the same concept: Equation: x^4 + 2x^3 - 9x^2 - ax + b So basically they want you to find the two missing variables in the 4th degree polynomial. They give you two roots to work with out of the possible 4. The roots they give you are: (x-1) and (x-2) 2. Relevant equations 3. The attempt at a solution I would think to use synthetic division and use one of the roots, but I'm not sure. Even if I'm coorect to use synthetic division what do I do once I reach the variables. I'm so lost.
