What is the factored form of x2 – x – 2?
(x – 2)(x + 1)
(x + 2)(x + 1)
(x – 2)(x – 1)
(x + 2)(x – 1)

Answer

(x – 2)(x + 1)

Explanation

x² – x – 2

The product of this equation = 1 × -2

                                                = -2

Sum = -1

Find 2 numbers that you can multiply to get -2 and when you add the same numbers you get -1.

The numbers are: -2 and 1

x² – x – 2 =  x² + 1x - 2x – 2

                =   (x² + 1x) - (2x – 2)

                = x(x + 1) - 2(x + 1)

                  =  (x - 2)(x + 1)

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
