I don't know if I should have expanded or not. now subtract 60 from both sides Now we need to use the rational roots theorem. So we know the only roots are factors of 30. So if we try x=5 we get so 5 is a root so x-5 is a factor. So by long division we get I hope this helps
thanks a lot. I just realized what I had to do, then I checked here and you guys helped. Thanks a lot
