Given:
( a + b )² - a² + b²
To find:
The value of ( a + b )² - a² + b²
Solution:
( a + b )² - a² + b²
We know that,
( a + b )² = a² + 2ab + b²
Therefore,
a² + 2ab + b² - a² + b²
2ab + 2b² ( +a² and -a² will get cancelled)
Further,
We can take 2b as common.
2b ( a + b )
Conclusion:
Therefore, ( a + b )² - a² + b² = 2ab + 2b² = 2b ( a + b )
