Want to help your student do well on the first TLI Test? Help them study quadratics! This si the key to the first test. Basically, note the second sign. If it's positive, then the signs were the same and you can look at the first sign to tell you what they were. If the second sign is negative, that means there is one sign of each in the binomials that made this trinomial. Then just find the factors of the last number that add or subtract to give the middle number!
