How To Find The Equation Of A Cubic

how to find the equation of a cubic

What is the equation to calculate cubic yards?
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,... pick four (x,y)coordinates (imaginary or useful) that you want it all to get to.Enter the matrix into your calculator. ie: for (2,4)(3,6)(5,12)(6,17) you would enter 8,4,2,1,4 for your first y equation. then the second row (3,6)of the matrix will follow the pattern of the first point (2,4).The the rest of your matrix will follow the same

Cubic Formula Cardano's method of solving a depressed cubic

Now we are looking at a cubic of the form , and if the roots take the form stated then, since their sum is now zero, we find that . But then the three roots are just the cube roots of , so they are the roots of the equation ....
So the trick is to find one real root, r, then divide the cubic equation by (x-r) to reduce the equation to a quadratic, and then it is easy to find the other two roots. A warning: If there are three different real roots, this formula won't work.
