Quick Q here

If equations with highest power 2 are called quadratic, 3 are cubic, 4 are quartic, what are equations with the highest power being 5 called?

Thanks

Pentathletes.

Quintic.

There is no analytical formula to obtain the roots of a quintic (or higher order) polynomial though, so they're not really something you would usually refer to specifically, other than as a 'higher order polynomial'. To find the roots of higher order polynomials you will in general need an iterative method.

Contradictions?

Well, I'm right - he's just having a laugh

Just google the words 'quintic equation'.

Sextic equations are next. An anyltical formula revolving around the value 69 can solve these within an hour on the average hard and floppy drive equipped PC.

What about when 8 = D ?
