i have a cubic equation and the coefficients are set already. But it always gives me the complex roots (all of them). As i know, root() function of the matlab (in practice and theory) gives the very approximate roots for any polynomial that has more than qu...
Roots:The roots of a function can be found when we equal our function to zero, another way to find the roots of the function is with the graph when it intercepts the x-axis.Answer and Explanation: We can find the roots of an equation when we turn it into the function, when we have...
This article presents information on how to solve cubic equations. The conventional version of the problem is to find the roots of the equation. Four things can happen with cubic polynomial roots. These consists of the various permutations of multiple roots and imaginary roots. Therefore, the ...

Roots and Critical Points of a Cubic Function Let’s suppose you have a cubic function f(x) and set f(x) = 0. Together, they form acubic equation: The solutions of this equation are called the
Express your equation: 12³ = 1,728, or 12 x 12 x 12 = 1,728 cubic inches. Step 5 Divide the result by the number of cubic inches in a cubic foot (1,728) if you need to find the total in cubic feet. In this example, since you started with a cube with 1 foot sides, 1...
