Ok so the equation is this: 3x^4-4x^3+8=0

When i solve for it, the calculator says this: False

Am i doing something wrong?

Can you tell me what i could do to get a number answer?(what should i press)

cZeros(3x^4-4x^3+8,x) (complex solutions because there is no real solution) instead of Zeros(3x^4-4x^3+8,x) (menu F2)

Also, my TI89 just gives {} when I press Zeros. If it yields false, check that you have no stored variable named x, or maybe because I have a titanium and I don't. - Aug 26th 2008, 01:42 PMtupac

Enable Pretty Print (on TI89 Titanium) to make the ugly complex numbers more readable.
