A rectangular swimming pool has an area of 18x^2 + 33x - 40.
Find an expression for the perimeter of this pool.
------------------
It might be 18x^2 + 33x - 40 by 1, making the perimeter
36x%5E2+%2B+66x+-+78
-------------
You're probably expected to factor that tho.
18x%5E2+%2B+33x+-+40+=+%286x+-+5%29%2A%283x+%2B+8%29
--> P+=+2%2A%28%286x+-+5%29+%2B+%283x+%2B+8%29%29
P = 18x + 6
