Find the total number of terms in `(1+x+x^2)^3`.

Explanation

To find the total number of terms in the expression \((1 + x + x^2)^3\), we can follow these steps:

### Step 1: Understand the expression
The expression \((1 + x + x^2)^3\) is a polynomial raised to the power of 3. We need to determine how many distinct terms will be present when we expand this polynomial.

### Step 2: Identify the components
The base polynomial \(1 + x + x^2\) consists of three distinct terms: \(1\), \(x\), and \(x^2\).
