Answers:

  • X = 4
  • Y = b
  • Z = 2a

========================================================

Step-by-step explanation:

Let's focus on the left side and try to transform it into the right side.


2b(2ab)^2 - a(2b^2)^2\\\\2b(4a^2b^2) - a(4b^(2*2))\\\\8a^2b^3 - 4ab^4\\\\4ab^3*2a - 4ab^3*b\\\\4ab^3*(2a - b)\\\\

When comparing that last expression to the form
XaY^3(Z-b), we see that:

  • X = 4
  • Y = b
  • Z = 2a
