# Week 6- precalc 11

This week in pre calculus 11 we learned how to solve quadratic equations, which at first the concept was a bit confusing but after working in the workbook started to get much easier because I was starting to see the patterns of the equations and expressions. Today we actually learned the third way of […]

This week in PreCalc 11 we revisited the idea of factoring polynomial expressions like we learned last year in grade 10. For example when we started the practicing of factoring expressions I remembered that for the second number in the trinomial it was the sum of adding the two numbers together and the third number […]
