Ok I have Psats, tomorrow, grade ten math. We are doing things like complex numbers and using foil to solve the algebraic expressions?
Lol I know l33t. But im just trying to make sure I'm doing everything correctly
1). (2+y) (6+y)
my answer is 12+2y+6y+y^2, Is that correct? If not can you explain in detail what I did wrong?

That's right, you're doing it correctly.
Thanks MreGsx had to be sure.
Just a quick side note:
If you need to go on to use your answer in a further question, may I suggest flipping your answer equation around, it just makes using it later on (maybe in simultaneous equations) 100 times easier.
Hello;
What Jamza means is put the values from greatest to smallest, or from your variables to your non-variables. So you should come out with: y^2+8y+12 (Make sure your "Y"s are together. You have to add all similar items. Like: 3x+4x = 7x. And so on.

I must have been sleeping that day...
I did foil in 8th grade..

Yes,In maths you want everything to Flow.
In Math you want everything to flow. Apparently English wasn't your subject :p

Yeah me too but certain schools/states do things differently. I know people who had to take physics then chemistry, then living environment, but it was the exact opposite for me
Put the variable before the number...
answer is y^2+8y+12
