1. The problem statement, all variables and given/known data Find the intervals of all possible value of p which the equation equation: (p-1)x^2+4x+(p-4)=0 has two different roots. 2. Relevant equations ax^2+bx+c>0 ?? 3. The attempt at a solution (p-1)x^2+4x+(p-4)>0 ?? How would I go about solving this? Is two roots >0 or =0?? Could I have an example so that I could then solve the problem on my own or steps I need to take in order to solve for the values of p.
