If we "plug in" p = b/a and q = -c/a, the formula indeed simplifies to the modern form of the quadratic equation as it is taught today. Various forms of the quadratic formula were used across Afro ...

The first attempts to find a more general formula for solving quadratic equations may have been made by Greek philosophers Pythagoras (c. 500 BC) and Euclid (c. 300 BC), who both used a geometric ...

The constructor for Parabola takes a string argument, which is the equation of the parabola in standard form. This is written using ^ as an exponent character. Custom regex is used to extract ...

A quadratic equation contains terms up to x 2. There are many ways to solve quadratics. All quadratic equations can be written in the form a x 2 + b x + c = 0 where a, b and c are numbers (a ...
