Rational Functions #7

You can use the Rarional zero test in order to find zeros. First, take the final number without a variable and write out all the factors of it. This will be your numerator. Then, take all the factors of your leading coefficient and that will be your denominator. Once you have solved for all the possible zeros, you must plug each one back into the original equation. Yes, this will take a lot of time and you will want to scream as I did. When you find a zero that makes your equation zero, then you know you have found a rational zero!
