Best ResponseYou've already chosen the best response.1then a^23a+(19289k)=0 Do you know that Ax^2+Bx+C=0? I use this B^2 4AC A=1, B=3, C=(19289k) So its be (3)^24.(1).((19289k)

Best ResponseYou've already chosen the best response.15+68k must be have 17 factor for some perfect square, 5+68k=17n 5=17n68k 5/17=(n4k) Found that its not integer, because there are 5/17.. even right side is integer. CMIWW @goformit100
