To determine if the expression \( 16x^6 + 4x^2 \) can be factored using the difference of two squares, let's first understand a few things about the expression.
1. **Identify the structure**: The expression \( 16x^6 + 4x^2 \) contains two terms, so it does not have more than two terms. However, it is an addition, not a subtraction.
2. **Difference of squares**: The difference of two squares is a factoring technique that applies to expressions of the form \( a^2 - b^2 = (a - b)(a + b) \). Notice that this involves a subtraction.
3. **Examine the terms**: For the difference of squares to be applicable, we need a subtraction (i.e., something of the form \( a^2 - b^2 \)). In our case, since both terms are added, that rule does not apply here.
4. **Perfect squares**: Additionally, even if the expression could be rewritten in a suitable form, both terms would need to be perfect squares, which they are: \( 16x^6 = (4x^3)^2 \) and \( 4x^2 = (2x)^2 \). Unfortunately, because the terms are added, we cannot use the difference of squares.
Thus, we can conclude that:
**Differences of two squares cannot be used because two terms are being added together.**
To further factor this expression, we can factor out the greatest common factor (GCF) first, but that would not involve the difference of squares method. The GCF of \( 16x^6 \) and \( 4x^2 \) is \( 4x^2 \):
\[
16x^6 + 4x^2 = 4x^2(4x^4 + 1)
\]
But as asked, the expression cannot be factored using the difference of two squares.
