When the sum of 6 and twice a positive number is subtracted from the square of the number, 0 results. Find the number.
The formula$$N=\frac{t^{2}-t}{2}$$describes the number of football games, \(N\), that must be played in a league with \(t\) teams if each team is to play every other team once. Use this information to solve Exercises 83-84. If a league has 36 games scheduled, how many teams belong to the league, assuming that each team plays every other team once?
