Answer:


\sf 4x^2 - 25

Explanation:

To expand the expression
\sf (2x + 5)(2x - 5), we can use the distributive property (FOIL method):


\sf (a +b)(a-b) = a \cdot a + ab - ab - b\cdot b

Using this:


\sf (2x + 5)(2x - 5) = 2x \cdot 2x + 2x \cdot (-5) + 5 \cdot 2x + 5 \cdot (-5)

Now, simplify each term:


\sf 4x^2 - 10x + 10x - 25

Combine like terms:


\sf 4x^2 - 25

So,
\sf (2x + 5)(2x - 5) simplifies to
\sf 4x^2 - 25.
