Hello!</h2>
The answer is:

<h2>
Why?</h2>
To solve the problem, we need to perform the operations and then, add like terms.
We need to apply the distributive property, which is defined by the following way:

Also, we need to remember how to add like terms. Like terms are terms that share the same exponent and the same variable, for example:

We were able to add only the first two terms since they are like terms, both are sharing the same exponent and the same variable.
So, we are given the expression:

Then, solving we have:

Hence, we have that the answer is:

Have a nice day!
