When simplifying a rational expression that is being multiplied or divided, factor first, simplify, then multiply top with top, bottom with bottom & state restrictions: no zeros in the denominator!
Ex: Simplify the following expression, stating any restrictions.
When solving inequalities – remember the goal is to either isolate x, or set one side to zero. Simplify as much as you can. Either draw a graph or use the number line method – show your work, including test value(s).
