Answer: the answer is 521
Step-by-step explanation: i don't know how i got it i am a human calculator :)
25a⁴ - 10a²z² - 8z⁴ <em>multiply 25*-8 = -200 to find factors (10*-20 = 200), (10 - 20 = -10)</em>
25a⁴ + 10a²z² - 20a²z² - 8z⁴ <em>factor the left two and right two terms</em>
5a²(5a² + 2z²) -4z²(5a² + 2z²) <em>one factor from each side should be identical</em>
= (5a² - 4z²)(5a² + 2z²)
