http://www.wolframalpha.com/input/?i=4x%5E2-x%5E2%2B4%3D0 it's a parabula ;)

anonymous · Answer

waitt..i needa know why or how u knw!!

anonymous · Answer

ok ok, resolve it right?

anonymous · Answer

put a variable t=x^2

anonymous · Answer

wait..wher did the "t" come from?

anonymous · Answer

so you will have 4t^2-t+4=0

anonymous · Answer

you create the t for help with calculus

anonymous · Answer

no@malevolence

anonymous · Answer

do you understand?

anonymous · Answer

this isnt calculus..this is alg 2, i dont understand what u are doing

anonymous · Answer

Ummm...
$$4x^2-x^2+4=0 \implies 3x^2+4=0 \implies 3x^2=-4 \implies x^2=-4/3 \implies$$$$ x= \pm \frac{2}{\sqrt3}i$$

anonymous · Answer

i just needa know wat graph it will make

anonymous · Answer

XD sorry man I just read x^4 my fault!

anonymous · Answer

decripter seems to knw wat im looking for...malevolence..i jus needa knw why its a parabola

anonymous · Answer

i didnt mean for u to get upset@malevolence

anonymous · Answer

I can tell you that if you take the x^2 you will have x^2*(4-1+4/(x^2)) so the graph with bigger value of x is like a parabola, but this is analysis I XD

anonymous · Answer

okay...i will just go ask sumone else
thnks for all of ur help
decripter...i kinda got wat ur saying..but ur calc language is strong! hahaha..thnks thou
