Given f(x) = x3 – 2x2 – x + 2, the roots of f(x) are
4 months ago
Q:
Given f(x) = x3 – 2x2 – x + 2, the roots of f(x) are
Accepted Solution
A:
You have the following expression given in the problem:
f(x) = x³ – 2x² – x + 2
Therefore, to find the roots, you must apply the proccedure shown below:
1. You have:
0 = x3 – 2x2 – x + 2
2. Then, when you factor, you obtain:
(x-2)(x-1)(x+1)=0
3. Therefore, you have that the roots are the following:
x1=-1
x2=1
x3=2
