I can't seem to figure this one out, so help would be greatly appreciated! Answer by jim_thompson5910(35256) (Show Source):
You can put this solution on YOUR website! Because this is cubic equation, this means that the solutions will not always be nice exact numbers.
So a decimal approximation is the next best thing, which means that you'll need to use your calculator to find them.
If you have a TI calculator, you can use the "zero" feature in the graph mode to find the solutions.
