Hi,

I'm abit confused with these two things. Firstly, I was taught this quick shortcut for dividing polynomials (although I struggle with using it for dividing by non-linear factors). I'll try explain it and see if anyone can help me with it.

To do it, using this example:

I write out the (x + 1) five times (since highest power is 5) and to make it like this:

(x + 1) (x + 1) (x + 1) (x + 1) (x + 1)

Then I'd go:

is the first number, since that's what needed to do the first power. That would leave

left. Then I'd need

to get to

so my equation would now look like:

Then so on until i get to:

and then I can factor to find solution is

Dunno if anyone else knows that method.
