August 26[edit]
minimum composite Quadratic...[edit]
Resolved
This is sort of shower though that I'm having problems working out. Let A, B & C be composite positive integers without a single common factor for all three (so 10, 12 & 15 would be allowed). Let the quadratic equation Ax^2+Bx+C be factorable into (px+q)(rx+s) where p,q,r &s are integers. Let Z=A+B+C. What is the minimum possible value for Z?Naraht (talk) 13:16, 26 August 2021 (UTC)
