SOLUTION: How do I factor this to find it's [sic] roots? f(x) = x^5 + x^3+2x-1 what I have is f'(x) = 5x^4 + 3x^2 + 2 Then I keep trying to factor it and run into problems like f'(x

Question 997566: How do I factor this to find it's [sic] roots?
f(x) = x^5 + x^3+2x-1
what I have is
f'(x) = 5x^4 + 3x^2 + 2
Then I keep trying to factor it and run into problems like
f'(x) = x^2(5x^2+3)=-2
f'(x) = x^2=(-2)/(5x^2+3)
I know that isn't right.
Please show the proper way. If possible without U-subs because I get tripped up with them.
=================
That can't be factored.
Were you asked to factor it, or to find the roots?
