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...
A Formula for Solving General Quintics: A Foundation for Solving General Polynomials of Higher DegreesI explore possible methods of solving general quintics and higher degree polynomials. In this paper I will attempt to show that each quintic has an auxiliary cubic equation. I will the...
[It's a big mess, all right, but are you surprised that there is a formula? It is called Cardan's Formula.] If your CAS can solve the general cubic equation, it can find a formula for the critical points of the general quartic. Do you think this formula is useful and/or usable?

A proportion is an equation with a ratio on each side. It is a statement that two ratios are equal. 3/4 = 6/8 is an example of a proportion. When one of the four numbers in a proportion is unknown, cross products may be used to find the unknown number. This is called solving th...
This maximization can be performed either directly by using any statistical software such as R (with the package AdequacyModel) or SAS (with the procedure PROC NLMIXED), or by solving the nonlinear likelihood equations obtained by differentiating ℓ(𝛼,𝛽,𝜉)ℓ(α,β,ξ) with respect ...
We develop a rigorous framework for general parameter estimation by solving survey weighted estimating equations which involve propensity score estimation for units in the non-probability sample. This development includes the expression of the variance estimator, as well as some alternatives which are ...
