Best ResponseYou've already chosen the best response.0Okay. Let me go through this one more time. Like terms means exactly what they sound like. suppose you had 5 apples and 4 oranges,. Could you add 5 apples to 4 oranges and say you have 9 apples? No, because apples are not oranges., so when you have something like (3y^2  7y  9)  (4y^2 + 6y + 9) , this means that you can add the y^2 terms together because they are like terms. Anyway, getting back to the problem. Suppose y^2 is apples. and y is oranges. (3y^2  7y  9)  (4y^2 + 6y + 9) means that you are subtracting 4 apples and 6 oranges and the number 9 from 3 apples and 7 oranges and the number 9. When you subtract 4 apples from 3 apples, you end up with 7 apples. when you subtract 6 oranges from 7 oranges, you end up with 13 oranges., subtracting 9 from 9 gives you 18. This means that you have 7 apples and 13 oranges and the number 18. In mathematical terms, this is 7y^2 13y 18

Best ResponseYou've already chosen the best response.0dw:1347826655400:dw no your not multipling you adding or subtracting exapmple so if I was at negative 9 or minus 9 then took 9 more then I'd be at 18 hence why we get 7y^213y18
