-x2%2B14x-45+
-1%28x%5E2+-14x%2B45%29
-1%28x-5%29%28x-9%29

See my Lesson Plans on Factoring on algebra.com, or see my own website by clicking on my tutor name "rapaljer" anywhere in algebra.com. Look for "Basic Algebra", then "Samples from Basic Algebra: One Step at a Time", "Chapter 2." There are several sections on Factoring, especially "Factoring Trinomials." See also my page called "MATH IN LIVING COLOR", then Basic Algebra, Chapter 2. It's all FREE and in COLOR.
