Please help me with this question

Answer 1

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
