Question 438431: Solve the indicated variable. A=P(2+r)^2. r=? That should be the power of 2. I'm not sure how to start. I know I have to get the r by itself but the P is throwing me off. If the P wasn't there I would have squared both sides. Any help would be greatly appreciated.

Solve the indicated variable. A=P(2+r)^2. r=?
----------
A=P%282%2Br%29%5E2
A%2FP+=+%282%2Br%29%5E2
2%2Br+=+sqrt%28A%2FP%29
r+=+sqrt%28A%2FP%29+-+2
