What are the basics of quadratic formula and function, how you can solve quadratic equations. A calculator for…
f(x)=y

$\lim_{x \to \infty} \exp(-x) = 0$

$f(n) = n^5 + 4n^2 + 2 |_{n=17} \,$

This is one really cool online math problem solver, with which you can find the roots of any expression (if any). Simply enter your problem in the field and click on the button to solve it. The rest will be done by our tool, just wait for several seconds.

Important note: To solve an equation with this tool, you need to write it in the appropriate form. As you can see, you have only one row, so you need to transform your problem into a one row expression. This is not that hard, you just need to use the following mathematical signs:

^ – scaling                                    * – multiplication
/ – division                                   x^1/2 = square root of x

An example for how the math problem should be formulated:    (5x^5+3x^4+5x^4+5x+8) / (3x+6)^1/2 = 3x    (you can copy and paste it to try the solver). After clicking on the button you will be able to see some detailed information about your expression like its chart, solutions and some other stuff. At the end of the post you can find the graph of this equation.
