Is it a factor?
If it is a factor, what is the remainder?
5
Let's use synthetic division to divide together.
This is one of two methods we can use!
6
Multiple Choice
What is the remainder, according to our work?

8
Let's use direct substitution to determine if the binomial is a factor.
This is the second method we can use! Does P(a) = 0?

Another Example
We won't do both methods again, but think... How do I know if it is a factor?

Here is the work. Now think to yourself, answer on the next slide: Is (x+3) a factor of P(x)?

Debrief
Learning Target: I can check whether or not a binomial is a factor of a polynomial.
Use synthetic division OR direct substitution.
If the remainder from synthetic division is 0, it IS a factor.
If P(a) = 0 from direct substitution, it IS a factor.
