1. The problem statement, all variables and given/known data Determine the range of values of the constant a so that the solution of ax^2+2ax+3>=0 (when a >0) is all real numbers 2. Relevant equations D = b^2-4ac 3. The attempt at a solution The discriminant is 0, 3. I need to know how to arrange them to get the range. The range is 0<a<=3 in the answers. How do I get it?
