I am trying to see the work of Omar Khayyam on cubic equations.
It seems that he solved some types of cubic equations.
However, I am not getting proper references for it.
Can anybody suggest a reference/references which "shows" original work of Omar Khayyam (means information with pictures from his book), and which gives clear information of what type of cubic equations he solved?
Note: I am not looking only references as mentioned here, but which give pictures from his book, as much as possible.
