Answers
GPT-4o mini
The expression \( k^2 - 225 \) is a difference of squares. It can be factored using the formula:
\[
a^2 - b^2 = (a - b)(a + b)
\]
In this case, we can identify \( a = k \) and \( b = 15 \) since \( 225 = 15^2 \).
Using the difference of squares formula, we can factor \( k^2 - 225 \) as follows:
\[
k^2 - 225 = (k - 15)(k + 15)
\]
So, the factored form of \( k^2 - 225 \) is \( (k - 15)(k + 15) \).
\[
a^2 - b^2 = (a - b)(a + b)
\]
In this case, we can identify \( a = k \) and \( b = 15 \) since \( 225 = 15^2 \).
