Help with factoring this one: x^9+1 (x^3+1) (x^3-x^3+1) Is this correct?

Great...i was adding the exponents that were on the outside instead of multiplying it. Took me a while to remember the rule. Thanks Ron.

Google "battle of bunker hill" and you will get a ton of information. It's now up to you to compact/summarize what you have learned into two hundred words.

Gotta remember those damn steps. I immediately assumed it was four terms so I factor by grouping. I forgot that you first look for common factor, then squares etc. Thanks.

having trouble factoring this particular problem x^2-12x+36-49y2 factored by grouping x(x-12) (7y-6) (7y+6) the answer in the book has (x-6+7y)(x-6-7y) confused.

Need help with factoring this problem. Just want to make sure I followed the right steps. X^3-2X^2-X+2 there are four terms so i used grouping method X^2(X-2)(-1)(X-2) (X-2) (X^2-1) (X-2) (X-1) (X+1) Correct?
