Just plug in those values into the function and see which one gives you zero.

i think it's -5, 1/3 and 1/2

tkhunny · Answer

You have to prove it.  No guessing or "I think it's".  Can you prove it?

Synthetic Division CAN help you.

anonymous · Answer

I can't but my son just did so that's good enough for me.  it's his work I'm trying to check, but I failed algebra in college so I'm pretty sure he knows more about this than I do.  Thanks for the help.

Good luck with that.  You may wish to consider a local tutor if he gets to far ahead for you to support him adequately.  You are awesome for giving it a go!
