# Week 5 PreCalc 11

This week we started factoring polynomial expressions. I learned how to take an equation like this $4x^2$-7x+3 and factor it into two binomials. I did this by using a box method and using CDPEU which stands for Common, Difference, Pattern, Easy and Ugly.

ex:

I even learned how to take an even uglier expression and factor it.

Ex:

I did this by changing (7x-5) to a and I did this to both of the (7x-5)’s.
