I'm going to use the remainder theorem. Look where it says "When we divide a polynomial f(x) by x-c the remainder r equals f(c)". You have to scroll down a bit on that page.

Let

Since we're dividing by , which is in the form where , we're going to plug in

So the remainder is actually 2.

Therefore, the initial claim is false.

Let me know if you need more help or if you need me to explain a step in more detail.
