数学小报4 - 三次方程的求根公式 The root formula for a cubic equation 1. 思考 我们学习过一元二次方程的求根公式 \(x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}\),思考是否存在一元三次方程的求根公式,便展开讨论。 补充 \(\o
An explicit formula for the cubic Szeg equationPatrick GérardSandrine Grellier
It is not a practical method for solving cubic equations. Instead, factoring or graphing are used to find the roots of cubic functions. How do you solve a cubic equation without a quadratic? There are two ways to solve a cubic equation without using a quadratic formula: factoring and ...
Hi, I've been trying to solve this equation for hours no, hoping somebody here can help. I have the equation: -2m2w2 + 15Bmw2 - 27B2 = 0 where m, B are unknown constants and I'm trying to solve for w. Is there a general formula for solving cubic equations? Thanks in advance...

The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation. If all of the coefficients a, b, c, and d of the cubic equation are real numbers, then it has at least one real root (this is true for all odd-degree polynomial fun...

Let's start off with our equation again: A = 10000 (1 + 0.03 / 12) ^ (12(10)) (note that ^ means 'to the power of') Using the order of operations we work out the totals in the brackets first. Within the first set of brackets, you need to do the division first and then th...
What is the formula for finding the surface area of a rectangular prism? To find the surface area of a rectangular prism, add the area of all faces together. The equation for determining this surface area is sa= 2(wl+hl+hw). How do you find the surface area of a cube? To find the...
The Ferrari method is a method for reducing the solution of an equation of degree 4 over the complex numbers (or, more generally, over any field of characteristic ≠2,3) to the solution of one cubic and two quadratic equations; it was discovered by L. Ferrari (published in 1545). =(x...
