3.1 Alg 2 Polynomial Long Division

What did we do with the remainder in writing the final answer?
5
What does it mean if there is a remainder?
6
What does it mean if there is NO REMAINDER?
7
Now we are going to apply this idea to POLYNOMIAL DIVISION. Here are the steps:
Step 1: Set up the problem. Are polynomials in standard form? is a placeholder needed?
Step 2: Divide, and write something on top
Step 3: Multiply by what is outside
Step 4: Subtract
Repeat until you cannot divide any longer.
Write final answer in proper format (if there is a remainder).
***If there is no remainder, that means the divisor is a factor of the dividend BUT IF THERE IS a remainder, the divisor IS NOT A FACTOR of the dividend.

Multiple Choice
When dividing polynomials, if there IS NO remainder, then
The divisor is a factor of the polynomial
The divisor is not a factor of the polynomial
The polynomials don't work
Then it is not a polynomial
