Question 188367
I guess you want to know what polynomials are for, right?

A polynomial is the sum of one or more terms.  (poly implies many)

Here are 3 sample polynomials:

(x^2 + 2x), (3x^3 + x^2 + 5x + 6) and (4x - 6y + 8) are all samples of polynomials.

They are very helpful in algebra, especially when answering algebra word problems and also solving math problems in real life.
