Step-by-step Solution
To factor the expression \( 16x^2 - y^2 \), we recognize that it is a difference of squares. The general formula for factoring a difference of squares is:
\[
a^2 - b^2 = (a - b)(a + b)
\]
In this case, we can identify:
- \( a^2 = 16x^2 \) which means \( a = 4x \)
- \( b^2 = y^2 \) which means \( b = y \)
Now we can apply the difference of squares formula:
\[
16x^2 - y^2 = (4x - y)(4x + y)
\]
Looking at the answer choices provided:
a) \( (4x + y)(4x - y) \)
b) \( (x + 4y)(x - 4y) \)
c) \( (x + y)(4x - y) \)
d) \( (4x - y)(4x - y) \)
The correct factorization is:
**a) \( (4x + y)(4x - y) \)**
So the answer is **a**.
Quick Answer
The correct answer is a. \( (4x + y)(4x - y) \).
