a4+b4-2a²b²


a²+b²-2a²b²


a³-b³-2ab


a²-b²-2ab​

Answer 1

Answer ↷

$(a²-b²)²=a {}^{4} −2a {}^{2} b {}^{2} +b {}^{4}$

Answer 2

Answer:

(a² - b²)² = a⁴ - 2a²b² + b⁴

Step-by-step explanation:

We must find,

(a² - b²)²

Now, we know that,

(x - y)² = x² - 2xy + y²

So, using the identity,

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

= a⁴ - 2a²b² + b⁴

Hence,

(a² - b²)² = a⁴ - 2a²b² + b⁴
