Answer 1

Step-by-step explanation:

this is the answer of your question

Answer 2

Step-by-step explanation:

This can be expanded by using an identity i.e, a² - b² = (a+b) (a-b)

We can also write (100x²-121y²) as:-

= (10×10×x×x) - (11×11×y×y)

= (10x)² - (11y)²

Now, using the identity → a² - b² = (a+b) (a-b), we can expand (10x)² - (11y)² as:-

→ (10x + 11y) (10x - 11y)

Therefore, the expanded form of (100x²-121y²) is → (10x + 11y) (10x - 11y)
