    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?

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

    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

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