Answer 2

(a - 2b)^2 + 2a^2b^2 - a^2 = 4b^2 - 2a^2b^2

Let's simplify this expression step by step:

Expand the square: (a - 2b)^2 = a^2 - 4ab + 4b^2

Now we have: (a^2 - 4ab + 4b^2) + 2a^2b^2 - a^2 = 4b^2 - 2a^2b^2

Combine like terms: a^2 + 2a^2b^2 - 4ab + 4b^2 - a^2 = 4b^2 - 2a^2b^2

Simplify: 2a^2b^2 - 4ab + 4b^2 = 4b^2 - 2a^2b^2

Now, subtract 2a^2b^2 from both sides: -4ab + 4b^2 = 4b^2 - 4a^2b^2

Subtract 4b^2 from both sides: -4ab = -4a^2b^2

Divide by -4a: ab = a^2b^2

Now, we have found a condition where the given equation holds true: ab = a^2b^2.
