Question

Given f(x)=2x^3-15x^2+22x+15
Find all real zeros

Answer 1

Answer:

Given function f(x) = 2x^3+15x^2+22x-15. Leading coefficient is p= 2,and constant q is 15. If p/q is a rational zero ,then p is a factor of ...

Step-by-step explanation:

Answer 2

1. Move all terms to one side x-2x^3+15x^2-22x-15x=0
2. Simplify
-21x-2x^3+15x^2-15=0
3. No root was found algebraically. However, the following root(s) were found by numerical methods.
x=−0.513248,2.806521,5.206728
