Question

( a+b) ^2-a^2+b^2
kkkkkkkkkkkkkkk​

Answer 1

Explanation:

`(a + b) {}^(2) - {a}^(2) + b {}^(2)`

a² + 2ab + b² - a² + b²

Cancelling a²

2ab + b² + b²

2ab + 2b²

Taking 2 and b as common

2b(a + b)

Answer 2

It is assumed the question is asking to simplify or factorize:

• (a + b)² - a² + b² =
• a² + 2ab + b² - a² + b² =
• 2b² + 2ab

This is simplified expression.

Factorizing as follows:

• 2b² + 2ab =
• 2b(a + b)
