So, we have.....

x^3 + x^2  = 230

It might be a little hard to find the soultion, algebraically.....we could use somerhing called "Newton's Method" to approximate a solution, but I prefer a graph......

The solution occurs at about (5.78, 230)

{x=((((3×i)2)(12))(9×((3568453(32))+(310427))(13)))+((3568453(32))+(310427))(13)×(((3×i)2)(12))(13)x=((3568453(32))+(310427))(13)×(((3×i)2)(12))+((((3×i)2)(12))(9×((3568453(32))+(310427))(13)))(13)x=(((3568453(32))+(310427))(13))+(1(9×((3568453(32))+(310427))(13)))(13)}
