Factor the trinomials , or state that the trinomial is prime. Check your factorization using FOIL multiplication. \(x^{2}-9 x+81\)
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. \(5 x^{2}-13 x+6\)
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 the quadratic equations by factoring. \(x(6 x+13)+6=0\)
