quadratic binomial

cubic trinomial

1 answer

To match the expression with its name, let's analyze the given polynomial:

Expression: \(3x^3 - 3x + 3\)

1. **Identify the degree of the polynomial**:
- The highest power of \(x\) in the expression is 3 (\(x^3\)), so the polynomial is of degree 3.

2. **Count the number of terms**:
- There are three terms: \(3x^3\), \(-3x\), and \(3\).

Since it is a polynomial of degree 3 (cubic) and it has three terms (trinomial), we can match the expression with its name:

**cubic trinomial**

Thus, the expression \(3x^3 - 3x + 3\) is a cubic trinomial.
