I am doing a placement study guide for my getting into college since I don't have my GED yet. I'm not so good at math much but I understand some. But anyway, I am stuck on a question for substituting values in algebraic expression. The question is If x = -3, what is the value of x^2 -1/x + 1?
Here is what I have so far and where I am stuck at. I don't know if it is correct or not:
x = -3
x^2 -1 -3^2 -1
------- = ----------
x + 1 -3 + 1
Please help with simple step by step instructions. Thanks!
