Answer 2

Answer:

( a + b ) ² = a² + 2ab + b²

Step-by-step explanation:

This is an algebraic equation which is used in adding and squaring 2 different types or variables...

Take an example:

( 4 + 5 ) ² = 4 ² + (2 * 4 * 5) + 5² (or simply 9² =  81)

= 16 + 40 + 25

⇒81.....

⇒( a + b ) ² ⇄ a² + 2ab + b²!!!!

I hope you have understood the expansion....
