See a solution process below:

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

#2ab - 3a + 4b + 5a + 4ab#

Next, group like terms:

#-3a + 5a + 2ab + 4ab + 4b#

Now, combine like terms:

#(-3 + 5)a + (2 + 4)ab + 4b#

#2a + 6ab + 4b#

If necessary, you can factor a #2# out of each term giving:

#(2 * a) + (2 * 3ab) + (2 * 2b)#

#2(a + 3ab + 2b)#
