A polynomial is an expression containing one term, or the sum of several terms which have the form
term =(real number)$\times$(power of a variable)$\times$(power of a variable)$\times$...$\times$(power of a variable)
The terms can contain one or more variables.
The $\text{degree of a term}$ is the sum of all the exponents in the variable part of the term.
Examples:
The term $(7x^{2})$ has degree $2$.
The term $(17x^{2}y^{4}z)$ has degree $2+4+1=7$.
The term $(xyz^{3})$ has degree $1+1+3=5$.
The $\text{degree of a polynomial}$ is the highest degree of its terms.
Example:
In the polynomial $(3x^{4}+2xy^{3}-5xy^{5}+x)$
the term with the highest degree is $-5xy^{5}$. Its degree is $1+5=6$.
So, the polynomial has degree 6.
