The price of a case of juice is $17. Fred has a coupon for $10.15 off each in the case. The expression to find the final cost of the case of juice is 17. Where b is the number of bottles. What are the terms and coefficient of the following expressions?

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.
