After solving, you will be left with 2#x# + 14.

Explanation:

Using the commutative property, move the 2 to the other side of the parenthesis. Like this:
2(#x# + 7)
Next, use the distributive property and multiply the 2 times #x#, then multiply 2 times 7. It should look like this after multiplying:
2#x# + 14
After all of this, you cannot simplify it any more.
The answer is 2#x# + 14.

#= x^2 +14x+49#

Explanation:

If the question was intended to be #(x+7)^2#, then we have:

#(x+7)(x+7)" "#multiply by multiplying each term in the first bracket by each term in the second bracket:

#= x^2 +7x +7x+49#

#= x^2 +14x+49#

NOte that this is in the form:

#(a-b)^2 = a^2 -2ab +b^2#
