How to simplify a cubic equation
Web1 Answer Sorted by: 3 Since x 2 + x + 1 is a factor of a x 3 + b x 2 + c x + d, there exist ( e, f) such that a x 3 + b x 2 + c x + d = ( x 2 + x + 1) ( e x + f) a x 3 + b x 2 + c x + d = e x 3 + ( e + f) x 2 + ( e + f) x + f From this, we have a = e, b = e + f, c … WebTo add the widget to iGoogle, click here.On the next page click the "Add" button.
