Answer:

(5x^2+4y)(5x^2-4y)

Step-by-step explanation:

25x^4-16y^2 has the form a^2-b^2 known as a difference of squares. It factors into (a+b)(a-b). To find a and b you take the square root.

\sqrt{25x^4} =5x^2

\sqrt{16y^2} =4y

The factored for is (a+b)(a-b).

In this case, it is (5x^2+4y)(5x^2-4y)
