Believe it or not, the first hints of the quadratic formula show up around 2000 BCE in ancient Babylon. That’s right—while we were still figuring out fire, the Babylonians were solving equations on clay tablets. They had a method for finding solutions, but it was all words, no symbols. Imagine reading, “Take half the number, square it, add it to the other number, and then…”—yawn.
These tablets, like the famous Plimpton 322, show they could solve problems like x² + x = ¾. But they didn’t write a neat formula. They were like the kid who knows the answer but can’t explain how they got it. Props, though—they started the math party.
