Use FOIL to find the products. \((x-5)(x+3)\)
Factor the trinomials , or state that the trinomial is prime. Check your factorization using FOIL multiplication. \(2 x^{2}+5 x-3\)
Solve the equations using the quadratic formula. \(6 x^{2}+6 x+1=0\)
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. If a league has 45 games scheduled, how many teams belong to the league, assuming that each team plays every other team once?
Solve each equation by the method of your choice. \(3 x^{2}-6 x-3=12-6 x\)
