Degree of cubic polynomial in two terms is :

Options

A. 0
B. 1
C. 2
D. 3

Answer

To determine the degree of a cubic polynomial with two terms, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of a Polynomial**: A polynomial is an expression made up of variables raised to whole number powers and coefficients.

2. **Identify the Degree of a Polynomial**: The degree of a polynomial is defined as the highest power of the variable in the polynomial. For example, in the polynomial \( p(x) = x^5 + 2 \), the degree is 5 because the highest exponent of \( x \) is 5.

3. **Define a Cubic Polynomial**: A cubic polynomial is a polynomial of degree 3. This means that the highest power of the variable \( x \) in a cubic polynomial is 3.

4. **Construct a Cubic Polynomial with Two Terms**: A cubic polynomial can have multiple terms, but it can also have just two terms. For example, we can consider the polynomial \( f(x) = x^3 + 2x^2 \).

5. **Determine the Degree of the Example Polynomial**: In the polynomial \( f(x) = x^3 + 2x^2 \), the highest power of \( x \) is 3 (from the term \( x^3 \)).

6. **Conclusion**: Therefore, the degree of a cubic polynomial, regardless of the number of terms, is always 3.

### Final Answer:
The degree of a cubic polynomial in two terms is **3**.
