## Why do you solve quadratic equations?

We also owe the Babylonians for the rather less pleasant invention of the (dreaded) taxman. And this was one of the reasons that the Babylonians needed to solve quadratic equations. Finding square roots by using a calculator is easy for us, but was more of a problem for the Babylonians.
