1. The problem statement, all variables and given/known data x (squared) + x - 30 _____________________ x (sqaured) -3x + 2 Find all numbers for which the rational expression is not defined. i know this is really easy stuff, but i have a hard time staying focused in math, and i have to always teach myself with the book, but sometimes the book isn't very informative. I have the answer, but don't know how to go about doing these problems. I know you like people to attempt them, but i don't even know where to begin after factoring the 30 .
