Those two numbers are the solution to the quadratic, but it takes students a lot of time to solve for them, as they’re often using a guess-and-check approach. Instead of starting by factoring ...

Plotting your graph. A quadratic equation is represented as a curve on a set of axes. In order to draw the curve on a graph we require several pairs of coordinates.These coordinates represent the ...

For instance, I mentioned Al-­Khwārizmī’s "completing the square" in order to solve a quadratic equation. It's actually a 4,000-­year-­old problem, dating back ...

Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, satellite dishes and the golden ratio.
