12. You need all the factors in each number to get least common multiple, 20 the two needs a 3 and another 2, the 4 needs a three and the twelve has everything it needs.
LCM needs two or more numbers to solve. The LCM of one number is itself.
You can't have the greatest common factor of just one number - for it to be common there needs to be at least 2 numbers.
You use the distributed property to find out if you have the same answer as you started out with. ex. 81x2+12t ...../....\..... ....9.....9...2....6 ..../\..../\.......|...... ...3..3.3.3xx.2....2.3t 3(27x2+2t) 3*27x2 3*2t 81x2+12t OR.. 9x2-1 = (3x+1)(3x-1) but to check it we multiple 3x and 3x to get 9x2 and theh 3x by -1 to get -3x then 1 by 3x to get positive 3x and then 1 and -1 to get a -1 so we end up with it looking like this 9x2-3x+3x-1 now since -3x+3x=0 we are left with the 9x2-1 the 9 needs to be multplied twice by the same number to get the number needed. so we have 9x2 needs to be broken up to 3x and 3x so that wen its multiplied we get 9x2 and for the -1.. we need to multiply the -1 by a positive 1 so that the can cancel out each other but we would get a -3x and a positive 3x that will cancel out each other to give us our final answer!
For a product to exist, there needs to be more than one number to multiply together.

There's no question there, and no problem that needs solving.The process described in the question yields the squareof the original number.

It's any real number distinct from 0. For instance, in the expression x/y, where x and y are real numbers, y needs to be a nonzero real number. This is because otherwise the expression x/y is undefined (viz. x/0).
a factor of a number is any number you multiply by another number to get it. . ..that probably needs an example, it sounds complicated. factors of 10 are 1, 2, 5, and 10, because any of those can be multiplied to another number to get you to 10. 12: 1,2,3,4,6,12 14: 1,2,7,14 see?
