See a solution process below:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

$7b - 5 + 7b + 5$

Next, group like terms:

$7b + 7b - 5 + 5$

Now, combine like terms:

$(7 + 7)b + (-5 + 5)$

$14b + (0)$

$14b$

How do you add (7b - 5) + ( 7b + 5)(7b - 5) + ( 7b + 5)?
