Amess: 4x^3+12x^2-26x-24=0
approximate any solutions to two decimal places.
I read your question wrong. I thought you had to estimate all of them and i thought that was a bit over the top.
Anyway you will need to use newton's method of approximating roots.
Show me what you can do and we'll take it from there (I haven't actually tried to do it yet)
I did a graph for you so you will at least know what you are trying to find.
