6x^3+38x^2+18x+2=0
This polynomial doesn't factor........here's a graph of the solution.....https://www.desmos.com/calculator/nncnoxpewo
There are three real roots at -5.828, -1/3 and -.172
(We actually could have found the second zero by using the Factor Theorem....this would have led to a quadratic that could be solved with the Quadratic Formula.....!! )
