Question 369340: Hi, I have to find all real solutions of the following:

I found all possible rational zeros: +/- [, , , ]
I graphed the equation and it looked like there was one zero at -.5 somehow, and I'm completely confused now :(
Thanks for any help you can provide, have a great night.

It looks like that but the actual zero is at .
I used Newton's method to find that root with a starting value of and it settled within 10 iterations.
The other 4 zeros are complex.
