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)
