You have the following expression given in the problem:
f(x) = x³ – 2x²<span> – x + 2
Therefore, to find the roots, you must apply the proccedure shown below:
1. You have:
0 </span><span>= 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</span>
Answer:
The answer is ±0.5 or ±1/2
Step-by-step explanation:
When you solve by using the quadratic formula, you get double roots that will solve the equation. Hope this helps!!
Answer:
the answer to your question is 0.857
Mixed number: 9 2/9
1. How many 9's go into 83
2. It is 9 because 9*9 = 81 9*10=90 is bigger so not possible
3. 2 is left because 83-81 = 2
4. And don't forget the denominator
Answer:
Would it not be 20?
