There is a very simple formula for finding the GCF. Just like I illustrated above but it's not a brute force method. What happens if you have to find the GCF for five different numbers? Brute force becomes confusing.

First you break every number apart into it's prime factors. Let's use an example of three numbers 42, 60 and 90
NB: ^ operator used to denote to the power of

42 = 2 x 3 x 7
60 = 2^2 X 3 x 5
90 = 2 x 3^2 x 5

So all three numbers share:
2 and 3 no other factors are shared amongst all the numbers so the GCF = 2 x 3 = 6

No matter how bad it gets, at least you won't start crying with snot running down your face during class cause you feel like you are looking at a foreign language.

I've just been there done that, dropped the last three days of class cause I knew I couldn't pass the final. Never felt so useless in my life. I took it hard. I don't like to feel stupid and I really did. Feel free to read the beginning posts in 2RS coffeeshop and know that you are far more advanced than I was in doing algebra so things aren't as bleak for you as it is for me. I literally start to get anxiety reading the page trying to solve these stupid tricky word math problems and stressed myself out far more than I should have.

I had just really made up my mind I was going to try to start a new career at mid life and saw that at this later age that I have a lot of limitations I didn't once have as a youngster.

Annie dragged me thru those days when I felt so miserable. I will never forget that.

Heart you Annie!

Good luck to you BALLS <<<<<------- this makes me laugh just typing it. I was going to call you BOR but I am sure you are far from boring :twisted:

2X+6=4x+ -2
X=?

basic but good, should be able to do it in your head fairly easy. Faster than the "proper steps" actually. My mental shortcuts screwed me later though as the steps and laws became more involved.

12x(2)y - 42x(2) - 4y +14. the 2s in parentheses are squared. im trying to factor it out but not getting the right answer. id like to know what im doing wrong. i keep getting (3x(2)-1) (4y+14) i know its wrong but this shits pissing me off lol

That's it. Everyone thinks it's about getting some number. The real point is to be able to show your work and rational. It's later when things get more confusing these basic bits of grammar are necessary.

So when Algebra starts back up for me in a couple weeks I can ask you for advice? lol
