1. **State the problem:** We are given the expression $8x^2$ and need to find the number of terms, the degree, the leading coefficient, and the constant term. 2. **Number of terms:** A term is a part of an expression separated by plus or minus signs. Here, $8x^2$ is a single term. 3. **Degree:** The degree of a term is the exponent of the variable. For $8x^2$, the exponent of $x$ is 2, so the degree is 2. 4. **Leading coefficient:** The leading coefficient is the numerical factor in the term with the highest degree. Here, it is 8. 5. **Constant term:** A constant term is a term without any variables. Since $8x^2$ has a variable $x$, there is no constant term, so it is 0. **Final answers:** - Number of terms: 1 - Degree: 2 - Leading coefficient: 8 - Constant term: 0
