Question 1135054
<font face="Times New Roman" size="+2">


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ x^5\ +\ x^3\ -\ 6x]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ x\(x^4\ +\ x^2\ -\ 6\)]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ f(x)\ =\ x\(x^2\ -\ 2\)\(x^2\ +\ 3\)]


Solve each of the factors for the real zeros.  Note that *[tex \Large (x^2\ +\ 3)] has no real zeros.

My calculator said it, I believe it, that settles it
