Factoring and expanding

Today in grade 11 we continues to work on factoring and expanding. We saw how the area model can be helpful when multiplying all kinda of things, like binomials, trinomials, and even mixed numbers. Arrows and the distributive property also work, but sometimes we can lose track of what we’ve multiplied.

Here are 2 groups who tackled the same question in 2 different ways. The area model allows us to see that like terms are all along the diagonal and easy to collect together.

We also had some practice working backwards with both common factoring and factoring trinomials. We watched 2 excellent factoring music videos as well to get us pumped up.
