a,b belong to N and a>1. p is prime .ax^2+bx+c=p for 2 distict integral values of x then the number of integral roots of ax^2+bx+c=2p?
 
 
Hello student, Please find the answer to your question below If a = b = N, then the roots of ax^2 + ax + c - p are -1/2 sqrt(1 - 4(c - p)/a)/2 which implies 1 - 4(c - p)/a is an odd square =...
