# The task is:

Write a React Redux app that is backed by a reducer that can do mathematical differentiation of polynomials:

For example, x^2 as input would give 2x^1 as output
3x^2+x+1 would give 6x+1

Input: 3x^2+2x+1
Output would be: 6x+2

And for input:
4x^3+3x^2+2x+1

Output would be: 12x^2+6x+2


More examples:

4x^3+3x^2+1 and the output should be 12x^2+6x
4x^3-5x^2+1 and the output should be 12x^2-10x

Please make sure there is test coverage for requests and method, and put it on a bitbucket/github that you share with me, username: cfeckardt


Your app should have:

A text field, where I can input my equation.
And just below it, and the derived expression in a <div> just below it.
If I input garbage data, I'd like to be warned about that too.
