Summation (or) sum is the sum of consecutive terms of a sequence. To write the sum of more terms, say n terms, of a sequence {an} , we use the summation notation instead of writing the whole sum manually. i.e., a1+a2+ +an=ni=1ai.
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.
