Aiden and I began by reviewing the definition of factor. We thought of it as a quantity that divides another quantity evenly. We use the example of 24 and listed all of its positive and negative factors. Next, I showed Aiden how factoring is the inverse(opposite) of the distributive property. We started with the example 3x+12. We considered that 3 was the greatest common factor between 3x and 12. So we factored out a 3 to consider what would be left. We realized that 3x+12=3(x+4). We checked with the distributive property that those expressions are equivalent. Next we discussed a problem with a negative leading coefficient. -2x-6. We explored two ways to factor this. If we factored out a 2 we would get 2(-x-3), if we factored out a -2 we would get -2(x+3). I explained to Aiden that when we have a negative leading coefficient, it's best practice to factor out the negative in order to keep what's left inside in simplest form. We will continue with this tomorrow.
