Dividing
Sometimes it is easy to didvide a polynomial by splitting it at the "+" and "-" signs, like this:
When I split the polynomail into two parts, I still had to keep the "/3" under each one.
Then the highlighted parts were "reduced" (6/3 = 2 and 3/3 = 1) to leave the answer of 2x-1
Here is another, slightly more complicated, example:
What happened? We couldn't simplify "1/3x" any further. So it has to stay like that. But the answer is still "simpler"
Now, sometimes it helps to rearrange the top polynomial before dividing, as in this example:
Long Division
If those methods don't work, you may need to use Polynomial Long Division
