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...

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?

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.

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..

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

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

sorry. it's 4 more girls

thank you.

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.

aaarrggh....ok thanks!

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

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.

THANKS!
