Title: How can I find the roots of a cubic function? Post by: michael_Stone on Sep 9, 2013 I need to know for homework. For example, what about this problem:
x^3 - 4x^2 + 6x - 4 That specific problem is not one I have to do, but it's similar. I am having an extremely hard time trying to understand how to do it, and it doesn't help that I struggle at factoring. Please try to be as specific as possible helping me. Is there any way to determine one of the roots besides guessing and checking? Title: How can I find the roots of a cubic function? Post by: daverightnow on Sep 9, 2013 first put some values for x.. like put x=1
(1-4+6-4) is not zero. So x=1 is not a root. then put x=2 (8-16+12-4) is zero. Therefore x=2 is a root for the above equation. do the division of the above equation by (x-2) then you'll get quadratic equation. I guess you know how to solve quadratic equation. All the best. :) Title: How can I find the roots of a cubic function? Post by: iLearninPhys on Sep 9, 2013 Content hidden
