Definition: In general, axn+bxn-1+.............+px+q (a is not equal to zero) is called a polynomial of degree n. Here the coefficients are either integers, rationals or both.

 Expression Polynomial Degree and number of terms 9 yes 0 degree monomial 2x2 + x - 5 Yes 2nd degree trinomial 12k6 - 7t No, variable exponent x-2-6 No, negative exponent 3ab4 + 5a2c2 5 5th degree binomial

Example: 3x2+9x3+6x5, find the degree of the polynomial.

Solution: The degree of terms in the above equation are 2, 3, 5 respectively. The greatest among these is 5. Hence the given polynomial is of degree 5.
