A polynomial is a mathematical expression that consists of variables and constants combined using addition, subtraction and multiplication. Variables may have non-negative integer exponents. Although division by a constant is allowed, division by a variable is not allowed.The degree of a polynomial is the exponent of the highest degree term.\tA polynomial of degree 0 is called a constant polynomial.\tA polynomial of degree 1 is called a linear polynomial.\tA polynomial of degree 2 is called a quadratic polynomial.\tA polynomial of degree 3 is called a cubic polynomial.
A polynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
