It is already in standard form. the degree is 3 and the leading coefficient is 5.
Explanation:
-
When the exponents decrease from left to right, the polynomial is in standard form. It is already in standard form the way you wrote it.
#5n^3 + 2n - 7# -
The degree of a polynomial is the highest exponent, which should be the first one if the polynomial is in standard form.
the degree of this polynomial is 3. -
The leading coefficient is just that: the first coefficient when the polynomial is in standard form. In other words, the coefficient of the term with the highest exponent.
the leading coefficient of this polynomial is 5.
