1. The entire expression is a sum with 3 terms.
2. The coefficients are 4, 1, and 3.
**Here are the 2 descriptions of the parts of the expression 4x^2+x+3:**
**1. The entire expression is a sum with 3 terms.**
* A "sum" in algebra refers to an expression where terms are added together.
* In this expression, there are three terms being added: 4x^2, x, and 3.
**2. The coefficients are 4, 1, and 3.**
* Coefficients are the numerical factors that multiply variables in algebraic terms.
* Here's the breakdown of coefficients for each term:
- **4x^2:** The coefficient is 4.
- **x:** The coefficient is 1 (even though it's not written, it's implied).
- **3:** The coefficient is 3.
