can someone please explain how to do this... GCF... x^2+6x-72
preferably in a way that is easier to understand than the book?
The whole deal with the "GCF" is to find a number that is the "smallest" number that can be divided into all terms evenly. So, from here, it looks like the answer is 1.
To find the GCF for variables. (in this problem we didn't have to consider variables seeing that 72 does not contain a X.) Just pick the variable with the lowest degree. (e.g variable with smallest power.)
ok I miss read the instructions, I need to factor this problem
Use the FOIL method. (x-6)(x+12)
Im sorry, to check to see if you factored "right" then use the FOIL method. But generally to factor a problem like this (e.g. leading term is a "squared" term than you have to find two numbers whos product equals the last number and whos sum equals the middle number of the original problem
see the FOIL method confuses me
In what ways does it confuse you?
well math period confuses me
Oh, lol.
i did well last week, but i tend to forget all concepts learned
To help with memorization, I would try to redo practice problems in the book. That should help, and if you need more hands on help I would try asking a friend or a teacher.
my friend's suck at math too and the one's who can do it are never available. this assignment has a due date and it takes forever for the teacher to respond
