You love challenging math problems. So do we. Let's solve them together. Quadratic equations are polynomials that include an x², and teachers use them to teach students to find two solutions at once.

The word "quadratic" comes from quadratum, the Latin word for square. Quadratic equations characterize a great number of phenomena in the real world, such as where a rocket ship will land ...

So why now? Loh thinks it is related to the way the conventional approach proves that quadratic equations have two roots. “Perhaps the reason is because it is actually mathematically nontrivial ...

If, while watching the Super Bowl, you had wanted to estimate how far a pass thrown by Patrick Mahomes traveled through the air, you would have been solving a quadratic equation. The equations ...

That year, French mathematician Évariste Galois finally illustrated why this was such a problem—the underlying mathematical symmetry in the established methods for lower-order polynomials simply ...

Invented by Leonardo Torres in 1920, the Torres calculating machine is a machine that solves essential addition, subtraction, ...

Save guides, add subjects and pick up where you left off with your BBC account. To sketch a quadratic function you must first determine the roots, nature and coordinates of the turning point and ...
