Math Smartasses

Bhaskara (Baskhara?) was a fukken smartass
oh sure, get his formula for resolving quadratic functions, that's just a smartass job

I did it yesterday pretty simply it too
and how come the formula gets his name?

I mean

have a ax² + bx + c = 0 formula and you wish to know the roots, this is how he did it:
ax² + bx = -c (*4a)
4a²x² + 4abx = -4ac (+b²)
4a²x² + 4abx + b² = b² - 4ac (factorising the left side)
(2ax + b)² = b² - 4ac
2ax + b = +- sqrt(b² - 4ac)
2ax = -b +- sqrt(b² - 4ac)
x = (-b +- sqrt(b² - 4ac))/2a

now seriously, is it really that difficult?
was he in college when he did this?
did he get a phd for it?

fuck math smartasses
I'm better than them.

So what, I worked out one for quintics yesterday, can't be arsed to write it out.

>>2
nice one, gb2 galois theory.

It's just that the resultant five equations are so long that it's prohibitive to actually print/write down, so no one bothers.  They exist though.

"However, there is no formula for general quintic equations over the rationals in terms of radicals; this is known as the Abel–Ruffini theorem, first published in 1824, which was one of the first applications of group theory in algebra. This result also holds for equations of higher degrees."

yes, but there are some quintic equations that are obviously soluble; >>2 was probably meaning implicitly those

Who said it was in terms of radicals, it's all in exponents.

It's quite an elegant theory, you wouldn't understand it.

>>7
ahem

>>3
You know that Abel Ruffini can be proven without Galois theory, right?

>>7
You misspelled "MY E-PEEN IS STILL LONG, RIGHT? DERP DERP"

Guys, it's alright if you don't believe me. Galois wasn't accepted by the mathematical community at first, but now he's recognised as a great mathematician.

In time my theory for the general solution to quintics will be as well known as his work, just wait and see.

>>11
You're an idiot, do you even know what Galois' work was about?

>>12

Rubik's cubes'n shit

>>13
I can solve the rubix cube, I used that to solve quintics
