How do I factor x^3 - 9x^2 + 15x +4? Can someone explain in steps please?
+130511 x^3 - 9x^2 + 15x +4
In general, there is no specific technique that might produce a solution. There is a method that sometimes works, but it can be tedious.
The fastest way is to set this to 0 and use a "solver" to see if there are any roots...here's a graph of the roots:
Notice the roots.....the (approximate) factorization is (x + .233) (x - 2.577)(x - 6.656).....
There's very little chance that you could ever "guess" this one !!!!!
In general....I'd let this one go.......
