Question 918125: how do i solve f{x) = 0, find the value of x? i am just starting algebra and having a hard time with it. Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! It really depends on what f(x) is.
You can graph it and look for where it crosses the x-axis but that's an approximate method and may require a lot of iterations to window in on a solution.

Some functions allow for simple algebraic solutions, such as,
So,
So,

Others are not so easy and require numerical methods to solve. being a recent example.
Solve using numerical methods, where approximately,

But you really need to know f(x) to know which way to proceed.
