Answer:
(x-2)(x+1)
- Step-by-step explanation: You basically want to see what the factors of -2 are. It is 1 and -2 or -1 and 2.
- You want to make sure which one of those will equal -x but can also equal an -2.
- When you do (x-2)(x+1); you can add the middle too numbers to see if you get the middle numbers
- if you did, then you can multiple it using the foil method to see if you get the same answer.
- So the middle would be -2x +1x. That would be a -x.
- then you would multiple the all to see if you get an x^2-x-2.
- WHen you do it it would come to x^2+1x-2x-2.
- Once you have that, you can add like terms to ge x^2-2x-2.
