**math Roots of a Quartic Function - Stack Overflow**

In algebra, a cubic function is a function of the form = + + + in which a is nonzero. Setting f(x) = 0 produces a If x ? r 1 is factored out of the cubic polynomial, what remains is a quadratic polynomial whose roots r 2 and r 3 are roots of the cubic; by the quadratic formula, these roots are either both real (giving a total of three real roots for the cubic) or are complex conjugates... Page 3 STEP 3 Seek Your Goal (Find the roots of the polynomial.) WHAT TO DO: Now comes the part where the spreadsheet really shines. 1.Control Select cells …

**Part 4 The Cubic and Quartic from Bombelli to Euler**

21/12/2012 · The general Quartic equation solving formula and examples.... Although it’s much bigger and less simple to deal with, there is a simple cubic equation solver in the form of the cubic formula. This is like the quadratic equation formula in that you just input your values of a , b , c and d to get a solution, but is just much longer.

## How To Work Out Cubic Quartic Formula

How to discover for yourself the solution of the cubic . This page is intended to be read after two others: one on what it means to solve an equation and the other …

- The other two roots (real or complex) can then be found by polynomial division and the quadratic formula. The solution proceeds in two steps. First, the cubic equation is "depressed"; then one solves the depressed cubic.
- 21/11/2018 · To solve a cubic equation, start by determining if your equation has a constant. If it doesn't, use the quadratic formula to solve it. If it does have a constant, you won't be able to use the quadratic formula. Instead, find all of …
