THANKS!

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

**math**

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.

Did some rethinking..is it 128x^16y^8 ?

**math**

multiply: (2x^4y^2)^3 (4x^2y)^2 Is this right? 128x^11y^8 Not sure.

aaarrggh....ok thanks!

last one on this topic i promise ;-) 4X-14+2X^3-7x^2 rearrange by degree 2X^3-7X^2+4X-14 and them im stuck..

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?

thank you.

sorry. it's 4 more girls

there are 4 girls in Mrs. Changs class than Mr. Blackwell's. 5 girls moved from Mrs. Changs to Mr. Blackwells. Now there are twice as many girls in Mr. Blackwells class as there are in Mrs. Changs, How many girls were in Mr. Blackwells class to begin with? Help, stuck with...
