For the implicit equation,

ax 3 + bx 2 + cx 1 + d 3 = b 2 - 4ac 1/2 ,

numerical methods will be needed.

Below is an equation with a radical relating to pentagonal symmetry:

3 5 - 2 5 inscribed sphere = 1/circumscribed sphere 5 + 2 5 15

ax 3 + bx 2 / ax 3 + bx 2 3 = b 2 - 4ac 1/2

2 b 5 + 3 5 + 1

a e -y - 1 e -y c + d y 1 + c / b - d e -y - 1 g b + 1 e -y

If your browser displays those equations correctly, it is enabled to display Design Science, Presentation, MathPlayer, ... MathML.
