Okay. 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

okay sounds good! :)

|dw: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^2-13y-18

@madisonmaruhnich94 : that's great. Always try to make those fancy x's and y's mean something that you can relate to.
