A polynomial is referred as a series of terms which are to be added to or subtracted from each other in an equation.
Best example of a trinomial would be 6x2-5x-6. For the ATC apprenticeship mathematics test you will work with factors to create polynomials.
A polynomial is referred as an algebraic expression in which the variables have non-negative integral exponents only.
Best example, all of the following expressions is polynomials:
17 + 2x + x2, x4 + 3x
The 1st & the last are polynomials in 1 variable x. The middle expression is a polynomial in 2 variables x & y. Therefore unless stated otherwise, polynomial will mean a polynomial in 1 variable. Operation of polynomials are classified following ways
a) Addition b) Subtraction c) Multiplication d) Division
