You can put this solution on YOUR website!
The rational root theorem states that if a polynomial $\"f%28x%29+=+a%5Bn%5Dx%5En+%2B+a%5Bn-1%5Dx%5E%28n-1%29\"$ + ... + $\"a%5B0%5D\"$ has a rational root, then it must be in the form +- a/b, where a is a factor of $\"a%5B0%5D\"$ and b is a factor of $\"a%5Bn%5D\"$ . So, if +- a/b is a rational root for your given polynomial, it might be -12/3 or 6/1 or whatever...you can try plugging in a few possible rational numbers for yourself. \n" ); document.write( "
