WebMay 30, 2024 · To get an explicit definition, we need to make the sequence above fit a quadratic function: At this point, you've probably been told to create a system of three equations using f (1) = 5, f (2) = 10, and f (3) = 17 in order to solve for a, b, and c. I'm happy to tell you that there's an easier way. WebMar 24, 2024 · The cubic formula is the closed-form solution for a cubic equation, i.e., the roots of a cubic polynomial. A general cubic equation is of the form z^3+a_2z^2+a_1z+a_0=0 (1) (the coefficient a_3 of z^3 may be taken as 1 without loss of generality by dividing the entire equation through by a_3).
