1. The problem statement, all variables and given/known data Find the equation of the polynomial of degree 4 with zero's at -2, 2, 1, 1 and a leading coefficient of 1. 2. Relevant equations ? 3. The attempt at a solution I don't know how to attack this one, I'm sure if I could see how to do it I could do it myself byt my head isn't working right now. All I can gather from that information is the first bit is x ^ 4 - Which isn't much. I'm thinking I have to substitue the values for zero into an equation and solve simultaneously? Can any one help?
