How do you expand algebraic expressions?
In order to expand and simplify an expression, we need to multiply out the brackets and then simplify the resulting expression by collecting the like terms. Expanding brackets (or multiplying out) is the process by which we remove brackets.
How do I expand a polynomial?
A polynomial is expanded if no variable appears within parentheses and all like terms have been combined. To expand a polynomial, multiply its factors (often by using the distributive property) or perform the indicated operations. Then combine all like terms.
