See a solution process below:

First, we can write the expression as:

#(7x^2 + 4x + 7) - (7x + 2)#

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

#7x^2 + 4x + 7 - 7x - 2#

Then, group like terms:

#7x^2 + 4x - 7x + 7 - 2#

Now, combine like terms:

#7x^2 + (4 - 7)x + (7 - 2)#

#7x^2 + (-3)x + 5#

#7x^2 - 3x + 5#
