if each participant of a chess tournament plays exactly one game with each of the remaining participants , then 136 games will be played during the tournament . find the number of participants .
let p be the number of participants . pc 2 = 136 ( p ) ( p - 1 ) = 272 = 17 * 16 p = 17 the answer is c .
divide(add(sqrt(add(multiply(multiply(136, const_2), const_4), const_1)), const_1), const_2)
