ex: x[2(x^2-5)] and so on. What do they signify?
it means that to solve the equation you must either: 1.solve what is in the brackets first or if that is not possible 2. the main subject outside the bracket by everything inside. 2x^3-10x First multiply out the first pair which is 2 with the (x^2-5)and then the x with what ever is the product of the 2(x^2-5) They signify that those in the brackets are not to be mixed by addition but instead multiplacation. Used becuase it is easier to represent the equation
The brackets mean that you have to do that bit in the brackets first!!
It means that u have to do it first or multiply it.
Brackets are the same as parentheses; you do them before the rest of the equation. Brackets are sometimes used when there needs to be more than one set of parentheses, like in the equation you've got.
