Multiply the polynomials and simplify: (x+5)(x−5) (1 point)
Responses

x2+10x−25x squared plus 10 x minus 25

x2−10x−25x squared minus 10 x minus 25

x2−25x squared minus 25

x2+25

Answer 1

To multiply the polynomials \( (x+5)(x-5) \), you can use the difference of squares formula, which states that \( (a + b)(a - b) = a^2 - b^2 \).

In this case:

- \( a = x \)
- \( b = 5 \)

So:

\[
(x+5)(x-5) = x^2 - 5^2 = x^2 - 25
\]

Thus, the simplified result is:

\[
x^2 - 25
\]

The correct response is:

**x²−25 x squared minus 25**.
