How extract common factors from brackets?
You use the distributive property. That is, you look for a common factor, divide each of the terms within parentheses, brackets, or whatever by this common factor, and write the common factor once outside the parentheses. For example: 10x + 15y Here you have a common factor of 5, so you can take this factor out: 10x + 15y = (10x + 15y) = 5(2x + 3y)
Does all the parentheses mean the same thing?
It depends what subject you use it for. For example, if you use parentheses in terms of language arts then, it would be the same thing no matter how you use it. In that case, it means you want to add extra information that isn't necessarily essential to the meaning. It can also be the definition of a term. If you use parentheses in math, then it can mean to multiply. It can also mean to work what is inside the parentheses first.
