case 1

Day 4 Clip 1

Prior to this clip, Ms. Coombs reviewed how distribution expands a polynomial in factored form.

 

Day 4 Clip 2

Ms. Coombs leads the students to use the distributive property to expand
y = (x + d)(x + e) as a way to test and generalize their hypothesis about how to generate the expanded form.

 

Day 4 Clip 3

Ms. Coombs leads the class through the factoring of the polynomial
y = x2 – 2x – 24.

 
Day 4 - Clip 3

Ms. Coombs leads the class through the factoring of the polynomial
