Do you know about synthetic division?

I have no idea , I had a question about that earlier , but no1 helped me . lol

anonymous · Answer

The coefficient of your highest term is 1, your x^0 term will be -3 once you put everything over on one side.  Therefore, if there are rational zeros, they will take the form of factors of 3 over factors of 1, so your rational candidates are +-3 and +-1.  If you don't know about synthetic division, for now, just plug those in one at a time to see what gives a zero and then we'll go to the next step.

By the way, are you sure you typed that equation in correctly?

Isn't that "=" sign supposed to be a "-" ?
