Solution :
So:
Let us simply the parenthesis first.
So we have
We can rearrange the terms and get:
Which is equal to
So now we have to complete it by multiplying it all by 1/4 which is basically dividing it by 4.
So:
Simplifying that, we get:
And reducing that farther we finally get:
Which is your final answer :)
