Solve the quadratic equations by factoring. \(x(6 x+23)+7=0\)
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?
Factor the trinomials , or state that the trinomial is prime. Check your factorization using FOIL multiplication. \(x^{2}+8 x+15\)
Use FOIL to find the products. \((x-1)(x+2)\)
Factor the trinomials , or state that the trinomial is prime. Check your factorization using FOIL multiplication. \(3 x^{2}-25 x-28\)
