The expression \( -7 b^{4} + b^{2} \) is a single-variable polynomial of degree 4.
Solución
Yes, the expression \( -7 b^{4} + b^{2} \) is a **polynomial**.
### Type of Polynomial:
- **Single-variable polynomial**: The expression contains only one variable, \( b \).
### Degree of the Polynomial:
- **Degree 4**: The degree of a polynomial is determined by the highest exponent of the variable. In this case, the highest exponent is 4 (from the term \( -7 b^{4} \)).
**Summary:**
\( -7 b^{4} + b^{2} \) is a single-variable polynomial of degree 4.

The given expression \( -7 b^{4}+b^{2} \) is indeed a polynomial! In this expression, the term \( -7 b^{4} \) has a degree of 4, while the term \( b^{2} \) has a degree of 2. Since the highest power of the variable \( b \) is 4, we classify this polynomial as a quartic polynomial, specifically of degree 4. Polynomials can be found everywhere! They pop up in physics for calculating trajectories, in finance for modeling profit curves, and even in computer graphics for creating smooth curves. This means that understanding polynomials can significantly aid in deciphering real-world phenomena, making them a crucial foundation in various fields!
