The degree of a polynomial is the highest degree of its terms when the polynomial is expressed in its canonical form consisting of a linear combination of monomials.

The degree of a term is the sum of the exponents of the variables that appear in it.

(i)The degree of the polynomial 5x³ + 4x² + 7x is 3.

(ii) The degree of the polynomial 4 – y² is 2

(iii) The degree of the polynomial 5t – √7 is 1

(iv) The degree of the polynomial 3 = 3x⁰ is 0.
