Answer:
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)
Step-by-step explanation:
[tex](a + b) {}^{2} - {a}^{2} + b {}^{2} [/tex]
a² + 2ab + b² - a² + b²
Cancelling a²
2ab + b² + b²
2ab + 2b²
Taking 2 and b as common
2b(a + b)
