I need help with my math homework, deals with factoring polynomials?

Question

[25(x^5)z-16x(y^2)z] this is the problem I've been having a difficult time with. I"m not sure how to factor this problem. Please teach me how you came up with solution. (intermediate algebra)

Answer 1

Unless you've written the problem down incorrectly, the only thing that I can see factoring out are the 'x' and 'z' which are common to both terms:

x * z * (25x^4 - 16y^2)
