(x+5)^2x-5)^2/x^2+25

Simplifying the Expression: (x+5)^2(x-5)^2 / (x^2 + 25)

This expression looks complex at first glance, but we can simplify it using some algebraic manipulations. Let's break it down step by step:

Recognizing the Difference of Squares

First, notice that the numerator consists of two squared terms: (x+5)^2 and (x-5)^2. This pattern fits the difference of squares formula:

a² - b² = (a + b)(a - b)

Let's apply this to our numerator:

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

Expanding the Expression

Now, we can expand the square in the numerator:

[(x+5)(x-5)]^2 = (x² - 25)²

Further Simplification

Finally, we can substitute this simplified numerator back into the original expression:

(x² - 25)² / (x² + 25)

This expression is now in its simplest form. We can't simplify it further without knowing the specific value of x.

Key Takeaways

  • Recognizing patterns like the difference of squares is crucial for simplification.
  • Expanding and simplifying expressions can lead to more manageable forms.
  • Sometimes, an expression can't be simplified further without specific values for variables.
