Polynomials in one variable are algebraic expressions that consist of terms in the form where n is a non-negative (i.e. positive or zero) integer and a is a real number and is called the coefficient of the term. The degree of a polynomial in one variable is the largest exponent in the polynomial. Note that we will often drop the âin one variableâ part and just say polynomial. Here are examples of polynomials and their degrees. So, a polynomial doesnât have to contain all powers of x as we see in the first example.
Let us discuss a few examples: 1  A polynomial in 2 variables: P(x,y) = x2 + 2xy + y2. 2  A polynomial in 1 variable: P(x) = x4 + 3x3 - 2x2 - 7. 3  A constant Polynomial: Q(x) = 3, R(x) = 5.
