Fast forward to ancient Greece. Euclid and his buddies got involved, but they were geometry snobs. They solved quadratics using shapes—squares and rectangles—because they thought numbers were too abstract. Imagine solving x² = 4 by drawing a square—classic Greek drama.
But the real hero here is Brahmagupta, an Indian mathematician from the 7th century. He wrote a rule that basically said, “If you have an equation like ax² + bx = c, just do this…” He even mentioned negative solutions, which blew everyone’s mind. Brahmagupta was the first to give a general method for solving quadratics, though it was still clunky. He deserves a high-five.
