The expression \( 4x^2 - 2x + 1 \) consists of three terms:
- \( 4x^2 \)
- \( -2x \)
- \( 1 \)
So, there are three terms in total.
The leading coefficient is the coefficient of the term with the highest degree. In this case, the term with the highest degree is \( 4x^2 \), and its coefficient is 4.
To summarize:
- Number of terms: 3
- Leading coefficient: 4
