Math questions, please help!!?

Question

I'm doing FOIL, and I understand it, but how can I do this question:
(y-1) 2

the two at the end means squared, I couldn't put it smaller and higher up, which is it's correct position.

PLease help, I'm desperate!! I really need to know the answer and how to work it out, it's important I understand this. Thanking you in advance! x

The letcurer did go over it in class, but I've been very ill recently and was absent. I'm catching up with work and need to understand this in order to complete the rest of this. If I can understand this question then I can do the others. I'm in college, not school - I have a lecturer, not a teacher.

Answer 1

Sorry I messed it up please read again:
ok the 2 will mean squared

(y-1)2 means (y-1)(y-1)
1. F the 2 first terms y x y which= y2
2. O the outer 2 terms y x -1 which = -y
3. I the 2 inner terms -1 x y which= -y
4. L the 2 last terms -1 x -1 which = 1

So finally you have y2 + -y-y + 1
Now the 2 y terms add to = -2y
leaving you with y2-2y+1 as your final answer

Answer 2

I am not in college but as far as I know (y-1)2 equals y2(squared) -1

Answer 3

I'm sure the teacher went over this in class, if it's that important for you to learn, you should pay attention to the teacher.

Answer 4

(y-1)(y-1)

Answer 5

(y - 1)^2 = (y - 1)(y - 1) = y^2 -y -y +1 = y^2 - 2y +1.

Answer 6

(y-1)^2=y^2-2y+1

Answer 7

y(squared) - 1(squared)

Answer 8

What is FOIL?

Sorry, I am of no help to you.
