How to Solve Cubic Equations?

How to solve cubic equations hire myAssignmenthelp.com Experts to Solve your any cubic Equation.a cubic equation always has at least one real root. The prior strategy of solving a cubic equation is to reduce it to a quadratic equation, and then solve the quadratic by usual means, either by factorizing or using a formula.

In mathematical terms, all cubic equations have either one root or three real roots. The general cubic equation is,

ax³+ bx²+ cx+d= 0

The coefficients of a, b, c and d are real or complex numbers with a not equals to zero (a ≠ 0). It must have the term x³   in it, or else it will not be a cubic equation. But any or all of b, c and d can be zero.

The examples of cubic equations are,

                          No 1,    x³+ 3a³+ 3 a² + a³– b=0

 No 2,    4x³+ 57=0 

  No 3,    x³+ 9x=0   

Strategy to solve cubic equation

Unlike quadratic equation which may have no real solution; a cubic equation always has at least one real root. The prior strategy of solving a cubic equation is to reduce it to a quadratic equation, and then solve the quadratic by usual means, either by factorizing or using a formula.

Always try to find the solution of cubic equations with the help of the general equation,

ax³+ bx²+ cx+d= 0

A cubic equation should, therefore, must be re-arranged into its standard form,
