Answer:


y=x^(3) -2x^(2) -x+2

Explanation:

You are given the roots 1, -1, and 2.

From there, you can combine all these factors into:

(x-1)(x+1)(x-2)

You know this because if you set these factors to 0, it will give you the roots 1, -1, and 2.

You can find the answer by multiplying all the factors and you get:


x^(3) -2x^(2) -x+2

Hope I helped :)
