Answer:

(2x - 5)(2x +5)

Step-by-step explanation:

4x^2 is a perfect square with a square root of 2x, and 25 is also a perfect square with a square root of 5. The difference of two perfect squares a and b can be written as [tex](\sqrt{a} - \sqrt{b} )(\sqrt{a} +\sqrt{b} )[/tex]. So, 4x^2 - 25 can be factored into (2x-5)(2x+5).

Hope that helped! ;)
