The polynomial is $\"\"$ .

Find the degree of each term or monomial.

The degree of a monomial is the sum of the exponents of all its variables.

The monomial is $\"\"$ , so its degree $\"\"$ .

The monomial $\"\"$ is a non zero constant, so its degree $\"\"$ .

The monomial is $\"\"$ , so its degree $\"\"$ . $\"\"$

Write the terms in descending order according their degrees.

$\"\"$ .

The standard form of a polynomial is $\"\"$ .

The coefficient of the first term in the standard form of polynomial is called leading coefficient.

So, its leading coefficient is negative 4. $\"\"$

The standard form of a polynomial is $\"\"$ and its leading coefficient is negative 4.
