Question

Help finding the complex zeros of a function! 
F(x)=x^4+2x^3+46x^2+98x-147

myininaya · Answer

147=3*7*7
---------------
147=21(7)
147=3(49)
Try using synthetic division with the following values 
x=+ or - {1,3,7,21,49,147}

Ok, so does it matter what I chose to divide by?

myininaya · Answer

It doesn't matter where you start but if you don't get the remainder zero you can throw the number you tried out.

Perfect!!! Thanks for your assistance you rock!!!

myininaya · Answer

Np. I like to at least try to guess ones that are more possible than others and try those because that is a lot to try. lol

anonymous · Answer

Ok, I did them all, and found there were no complex zeros do you think that's correct!

myininaya · Answer

Nope. :(
