I need help bad i been doing this homework since i got home at 4:00 and am stuck on this problem.

X -1 : X-2 =sum (x+1)+(x-2)=(x+x+1-2) diff (x+1)-(x-2)=(x-x-1-2) Product (x-1)(x-2)=(x^2-1)

sum (x-1)+(x-2) = 2x-3

diff (x-1)-(x-2) = 1
prod (x-1)*(x-2) = x^2-3x+2

looks like you need some review on working with basic operations.

It seems like you are working on an algebraic expression involving the variables X, X-1, and X-2. From your description, you have used different operations like addition, subtraction, and multiplication to combine these expressions.

Let's break down the steps you have followed:

1. Sum: You have combined the expressions (X+1) and (X-2) by adding their corresponding terms. The sum of (X+1) and (X-2) is (X+X+1-2) or (2X-1).

2. Difference: You have subtracted the expression (X-2) from (X+1). The difference between (X+1) and (X-2) is (X-X-1-2) or (-3).

3. Product: You have multiplied the expressions (X-1) and (X-2). The product of (X-1) and (X-2) is (X^2-1).

If you are stuck on a specific step or need further assistance, please let me know.
