Create a venn diagram (with a minimum of 4 points) to compare and contrast two of the managed care reimbursement methods listed: percent-of-charge payment, per diem payment, case rate payment (drgs and ms-drgs), ambulatory patient grouper (apg), ambulatory payment classification (apcs), other types of reimbursement (carve-out, stop-loss, and withhold pools)

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
