You can put this solution on YOUR website! I don't quite understand what you mean by saying "is there a solution"........but for explaining that qudratic equation:....the equation can be factored making it(p-2)(p-2)=0 giving you the root +2 .......This probabally wont make much sense to you because I didn't explain it very well, since I havn't done algebra for months now.....
You can put this solution on YOUR website! p^2-4p+4=0 [Factor or use the quadratic equation]
(p-2)(p-2)=p^2-2p-2p+4=p^2-4p+4

p=4/2=2
p=2
p-2=0
(p-2)(p-2)=p^2-4p+4
