if each participant of a chess tournament plays exactly one game with each of the remaining participants , then 276 games will be played during the tournament . find the number of participants .
"let p be the number of participants . pc 2 = 276 ( p ) ( p - 1 ) = 552 = 24 * 23 p = 24 the answer is c ."
divide(add(sqrt(add(multiply(multiply(276, const_2), const_4), const_1)), const_1), const_2)
