In the polynomial $$ 3x^{5} + 2x^{3} - x^{1} + 9 $$, what is the leading coefficient?

Question

UpStudy AI · Accepted Answer

In the polynomial $$ 3x^{5} + 2x^{3} - x + 9 $$, the **leading coefficient** is the coefficient of the term with the highest degree (the largest exponent of $$ x $$).

Let's break it down:

- **$$ 3x^{5} $$**: Degree 5, coefficient is **3**
- $$ 2x^{3} $$: Degree 3
- $$ -x $$ or $$ -x^{1} $$: Degree 1
- $$ 9 $$: Degree 0 (constant term)

The highest degree here is **5**, and the coefficient of $$ x^{5} $$ is **3**.

**Answer:** 3
The leading coefficient is 3.
