Answer 2

`\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`.
