2 questions here, both kind of inequality related:
1. |1-x|=1-x; I know the answer is x less then or equal to 1, but I don't understand why or how.
2. x^3-6x^2+5x+6 less than or equal to 0. It says to use a sign line to figure out the answers. I know how to get the roots, I just don't know how to get the inequalities.
