Answer:
We want to expand the expression:
We can just do it by brute force, this is:
First, rewrite our expression as the product of two square factors:
Now we can expand each one these two factors:
That can be simplified to
Now we can replace that in our original expression to get:
Now we can expand that last product, to get:
We can simplify that to:
That is the expanded expression.
