This week in math ten i learned how to reverse a foil equation(factoring). doing foil is much like doing distributive property although it is divided into two brackets. Factoring polynomials is like breaking the equation down and finding its original numbers that made up the equation. Sometimes the equation can have a pattern, they can all divide by the same number. for example, this equation can be divided by eight.I also went further and reduced the 4 to a prime number, 2.
