Question

find the value of (a+b) (a+b)​

Answer 1

• Answer

→ (a + b)(a + b)

→ (a + b)² (use identity)

→ a² + b² + 2ab

Answer 2

Answer:

Step-by-step explanation:

( a + b ) ( a + b )

Removing the brackets

a * a + b * a + a * b + b * b

$a^2+ ba + ab + b^2$

$a^2 + 2ab+b^2$

                                              ANOTHER METHOD

( a + b ) ( a + b)

This can be written as

$( a + b )^2$

We know  that

$( a + b )^2$ = $a^2 + 2ab+b^2$
