Solve the equations in Exercises 53-72 using the quadratic formula. \(x^{2}+8 x+15=0\)
Factor the trinomials , or state that the trinomial is prime. Check your factorization using FOIL multiplication. \(3 x^{2}-25 x-28\)
Determine whether each statement makes sense or does not make sense, and explain your reasoning. In an inequality such as \(5 x+4<8 x-5\), I can avoid division by a negative number depending on which side I collect the variable terms and on which side I collect the constant terms.
Solve each equation by the method of your choice. \(2 x^{2}-9 x-3=9-9 x\)
Solve the equations using the quadratic formula. \(x^{2}+2 x=4\)
