16-b^2

The expression \(16 - b^2\) can be factored using the difference of squares formula, which states that \(a^2 - b^2 = (a - b)(a + b)\).

In this case, we can rewrite \(16\) as \(4^2\), so:

\[ 16 - b^2 = 4^2 - b^2 \]

Using the difference of squares formula, we factor it as follows:

\[ 16 - b^2 = (4 - b)(4 + b) \]

So the factored form of \(16 - b^2\) is \((4 - b)(4 + b)\).
