For the parabola \(y=(x+6)(x-4)\) determine the coordinates and nature of its turning pont and the equation of the axis of symmetry. The roots are \(x=-6\) and \(x=4\). The aixs of the symmetry is ...

An animated guide to factorising quadratic expressions and equations. Examples are used to show how to find factors that multiply to give the number term and add to give the x coefficient in an ...

The only real problem is not many quadratic equations have A=1. For example, suppose you throw a ball straight up from 5 meters above the ground with a velocity of 15 m/s. We want to know when the ...

That year, French mathematician Évariste Galois finally illustrated why this was such a problem—the underlying mathematical ...
