Degree is the highest power of the exponent in the polynomial.
A third degree polynomial is of form
. Its degree is 3.
This polynomial is in standard form as the terms are ordered from the biggest (3) to the lowest exponent (0).
B.
A polynomial is an expression consisting of variables and coefficients combined together using arithmetic operations. Exponents of variables are non-negative integers.
Polynomials are closed under addition as sum of two polynomial is also a polynomial.
For example: take two polynomials as![x+2,2x^2+4x+9](/tpl/images/0661/0046/3dabe.png)
