Example Find the equation of the line of symmetry and the coordinates of the turning point of the graph of y = x 2 6 x + 4. Writing y = x 2 6 x + 4 in completed square form gives y = (x 3) 2 5.

In a boon to algebra students everywhere, a professor at Carnegie Mellon University has devised a simpler and more efficient way to solve problems involving the quadratic equation.

Learn about and revise quadratic equations by factorising, completing the square and using the quadratic formula with GCSE Bitesize OCR Maths.

The quadratic formula learned by generations of math students is difficult to remember, but it can be used to solve quadratic equations where y = 0.

Most people’s experiences with polynomial equations don’t extend much further than high school algebra and the quadratic formula. Still, these numeric puzzles remain a foundational component ...
