On September 8, 2025, Google launched a special animated Doodle titled “Learning the Quadratic Equation” to welcome the new school year. The Doodle appeared across multiple countries and featured one of the most searched mathematical formulas: ax² + bx + c = 0.
The Doodle highlights key themes of mathematics and engineering, shining a light on the importance of this timeless equation. Often regarded as a cornerstone of algebra, the quadratic equation has countless real-world applications. In physics, it helps calculate motion—whether predicting the arc of a basketball shot or charting the trajectory of a spacecraft. In engineering and business, it is used for solving optimization problems, design challenges, and much more.
Beyond the colorful animation, Google encouraged users to dive deeper into the concept using its AI-powered search mode. This feature allows students and lifelong learners to ask questions about the quadratic equation and receive detailed, interactive answers along with links to relevant resources.
By combining technology with education, this Back-to-School Doodle not only celebrates mathematics but also inspires curiosity, showing how a formula written centuries ago continues to shape the modern world.
