Question

A² + 2ab + b^22a^4 - 2b^4​

Answer 1

a² - 2ab + b² = (a + b)²

$2a {}^{4} - 2b {}^{4} = 2( {a} - b)(a + b)(a {}^{2} + b {}^{2} )$

или...

a+b / 2a³ + 2ab² - 2a²b - b³

Answer 2

It looks like you've provided an expression that involves variables a and b raised to different powers. However, the expression seems to be a bit unclear due to missing operators and parentheses. Could you please provide the expression with proper formatting and indicate what you'd like to do with it? Are you looking to simplify it, factor it, or perform some other operation?
