**Ferrari's method of solving a quartic equation**

Quartic. Solve Quartic equations (4th degree polynomials) in C and Haskell. License: BSD. (Also solves cubic, quadratic, and linear equations) The two implementations are very close in their structure/design.... 2.5 Necessary and sufﬁcient condition for (2.4.3) to be a perfect square We know that since (2.4.3) is a quadratic in y a necessary and su cient

**How to solve a quartic equation Quora**

A quartic spline was chosen as a cubic proved of insufficient accuracy for the calculation of the curvature. From Cambridge English Corpus A close-up view of the c4(+r) = 1.5 contour near the quartic point for the three-layer 1 system (6).... Now we know how to solve cubics, so solve for y. With this value of y the right hand side of (*) is a perfect square so, taking the square root of both sides, we obtain a quadratic in x . Solve this quadratic and we have the required solution to the quartic equation.
