straight x squared minus open parentheses straight p squared minus 9 close parentheses straight x plus 8 equals 0 comparing space with space ax squared plus bx plus straight c equals 0 we space have straight a equals 1 straight b equals negative open parentheses straight p squared minus 9 close parentheses straight c equals 8 now sum space of space roots space equals space fraction numerator negative straight b over denominator straight a end fraction equals 0 space fraction numerator open parentheses straight p squared minus 9 close parentheses over denominator 8 end fraction equals 0 straight p squared equals 9 straight p equals plus-or-minus 3
