To determine if the expression \( 36x^5 - 2x \) can be factored using the difference of two squares, we first need to recognize the form required for this type of factoring.
The difference of two squares states that \( a^2 - b^2 = (a-b)(a+b) \). In order to use this method, the expression needs to consist of exactly two terms, one of which is subtracted from the other.
Let's analyze the provided expression \( 36x^5 - 2x \).
1. **It has 2 terms**: The expression consists of \( 36x^5 \) and \( -2x \).
2. **Both terms are perfect squares**: We need to check if they can be expressed as squares.
- \( 36x^5 \) can be rewritten as \( (6x^{5/2})^2 \) (but \( x^{5/2} \) is not a perfect square).
- \( 2x \) is not a perfect square either.
So, neither term in the expression is a perfect square.
3. **Difference of squares**: The expression is indeed of the form \( a^2 - b^2 \). However, since neither term can be expressed as a perfect square, we cannot factor it using the difference of two squares.
Given these observations, the most fitting statement from your options is:
**Differences of two squares cannot be used because all terms are not perfect squares.**
