Save guides, add subjects and pick up where you left off with your BBC account. Here are some examples of quadratic equations in this form: \(2x^2 - 2x - 3 = 0\). \(a = 2\), \(b = -2\) and \(c ...

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 ...

A quadratic graph is produced when you have an equation of the form \(y = ax^2 + bx + c\), where \(b\) and \(c\) can be zero but \(a\) cannot be zero. All quadratic graphs have a line of symmetry.

This problem can be written down as a quadratic equation of the form Ax 2 +Bx+C=0 ... wide range of other ways to derive the formula. But all of them are also tricky and non-intuitive.
