Many former algebra students have painful memories of struggling to memorize the quadratic formula. A new way to derive it, overlooked for 4,000 years, is so simple it eliminates the need.

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 ...

Learn and revise how to solve quadratic equations by factorising, completing the square and using the quadratic formula with Bitesize GCSE Maths Edexcel.

For a quadratic equation of the form, ax 2 + bx + c = 0, a ≠ 0 to have two equal real roots, its discriminant must be equal to zero, i.e., D = b 2 –4ac = 0 Given equation is 2 x 2 – kx + k = 0 ...

Solution: Yes, a quadratic equation having coefficients as rational number, has irrational roots. For example, the quadratic equation x 2 – 4x – 3 = 0 has rational coefficients.
