Week 8 – Math 10 – Product sum

Product sum:

In week 8 we learned about product sum. This one in particular is my favorite out of Factoring 123. It is very useful for trinomials. 

To begin, look at the second and third term. Find a set of numbers that multiply to make the third term (the constant), and add to make the second term. 

Example: 

Vocabulary: 

Trinomial: polynomial with 3 terms 

Constant: fixed value, no x
