16x^4 - 200x^2 + 625?

Factor.

If you do not want to tell me what the answer is, please tell me how to solve...because I can't figure it out. But, if I understood what to do, I could answer it myself.

Also, I am not sure, it might be prime.

It's like a² - 2ab + b² = (a + b)² with a = 4x² and b = 25

16x^4 - 200 x² + 625 = (4x² - 25)(4x² + 25)

now 4x² -25 is like a² - b² = (a - b)(a + b)
