good job anyway, you wrote almost the same :D
P.S. if any1 got bored,
Solve the system of equations algebraically:
y=x^2-x-20
y=3x-15
hf
oh and ofc nice jumps kafds, i suck atm
HAahh I will when I get back home, i'll edit just to fuck with chosANN!! Anyway I got to doubleroot info up there but fucked up when calculted wrong one :D

slowmo, but gj!
Lolo, nice edit.

OK so..
Basicly 3x - 15 is a linear straight which is having it's zero points with x-axle at (5; 0).
x^2 - x - 20 is a parabola opening upwards, x-axles zero points (2) at (5 ; 0)
and (-4 ; 0)x^2 - x - 20 is a parabola opening upwards, x-axles zero points (2) at (5 ; 0)
.'.
With only this information I can find already one solution to this one. (5 ; 0)
Anyway marking y = y gives us both answers we are looking for:
3x - 15 = x^2 - x -20 || every term to one side and zero to other*blabla*
Leads us to second quadratic equation (second degree)
x^2 - 4x - 5 = 0, once again using quadratic formula.
x = 4 +(-) sqr 16 - (-20) divided by 2 x 1 (=2)
x1 = 4 + 6 divided by 2 (= 5) ; x2 = 4 - 6 divided by 2 (=-1)
So the parabole and the linear straight are meating in two different spots which are (x ; y) = (5 ; 0) and (-1 ; -18)
(I had no time to more detailed representation. anyway I got the cordinates.)

For your own good, please download it - the stream-links are bugged in a very weird way; their playing speed is almost DOUBLED from what it should be. I have no idea how that bug appears and it occurs in YouTube AND own3D.tv.

cmon now i see all kinds of mathematical shit stuff in school everyday.. not in here aswell plx :ASD:AS:DA:SDADASASD

hmm the reason why its bugged on yt is because of mp4, my mp4 was bugged for youtube, then i started using mkv and it never bugged, the reason i said to ask me for quality shit
