Question

simplify the expression (a²+b²+2ab²)+(a²-b²-2ab)​

Answer 1

Answer:

a^4 - b^4 - 4ab³ - 4a²b²

Step-by-step explanation:

= (a² + b² + 2ab) + (a² - b² - 2ab)

= a²(a²- b² - 2ab) + b²(a²- b² - 2ab) + 2ab(a² -- b² - 2ab)

= a^4 - a²b² - 2a³b + a²b² - b^4 - 2ab³ + 2a³b - 2ab³ - 4a²b²

=a^4 - b^4 - 4ab³ - 4a²b²
