They can have one or many variables in any combination ... uses the idea of the two roots of every quadratic equation to make a simpler way to derive those roots. He realized he could describe ...

Enter Po-Shen Loh, a mathematician at Carnegie Mellon University in Pittsburgh, who has found a simpler way—one that appears ... proves that quadratic equations have two roots.

Over the centuries, mathematicians have developed a variety of methods of solving equations ... that can pull the given root-finding method into any one of the four roots of z 4 – 1 = 0.

This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...

The equation factorises to give \((x – 3)(x – 3) = 0\) so there is just one solution to the ... x^2 + 2x + 5 = 0\) has no roots. The graph of the quadratic equation \(y = ax^2 + bx + c ...
