'What is a satisfactory quadratic equation solver?'

'Finite-difference methods for partial differential equations'

'How do you solve a quadratic equation?'

For the most part it can. if you have a TI-83 or better, you can use the solver under your math button. All you have to do is plug in the equation that is set to equal zero!

One of the best online equation solvers available can be found on the website Wolfram Alpha. The website accepts equations and most types of query, and returns an answer with proofs.
