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

All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic function y = a x 2 + b x + c is a smooth curve with one turning point.

Some common examples of the quadratic function Notice that the graph of the quadratic function is a parabola. This means it is a curve with a single bump. The graph is symmetric about a line called ...

If your high school math is a little rusty, Sherbo says a quadratic equation is a handy tool to model natural phenomena like projectile motion.

This paper gives an alternative proof of the law of quadratic reciprocity that hinges on some well-known facts about Euler's criterion, the existence of primitive roots, and basic properties of the ...

This paper develops a quadratic function convex approximation approach to deal with the negative definite problem of the quadratic function induced by stability analysis of linear systems with ...
