Answer 2

Solution

Step-by-step explanation:

we must apply BODMAS RULE

ie first Bracket open then OF then DIVIDE then MULTIPLY then ADD and at last SUBTRACT

$\huge\boxed{{\bf { (a + b) - (a - b){}}}}$

$\huge\boxed{{\bf { = a + b - a + b{}}}}$

$\huge\boxed{{\bf { = a - a + b + b{}}}}$

$\huge\boxed{{\bf { = 2b{}}}}$
