Question

Oh my this is just too hard for me...how do i solve this..
x^5 - x + 1 = 0

Answer 1

Is this \(x^2-x+1=0\) ?

Answer 2

no \[x^{5} -x +1=0\]

Answer 3

hmm.....

Answer 4

a quintic equation

Answer 5

\(x^5-x=-1\)

Answer 6

nop quintic...

Answer 7

sorry!

Answer 8

and its so hard to solve i don know

Answer 9

i m trying ok :)

Answer 10

ok

Answer 11

this quintic equation's root can't be expressed as radicals .

Answer 12

No idea for the answer but does it help to start with:\[x \left( x ^{4} - 1 \right) = 1\]?

Answer 13

mmm...i think i can try from there...luckily i have the answer with me...

Answer 14

visually, the answer is somewhere ]-1.2;-1.1[

Answer 15

I don't know if it will converge, you could try Newton's method:

Make a guess, say -1.25 (x_0) then

x_1 = x_0 - f(0)/f'(0) and repeat till u get close..

Answer 16

yeah i tried Newton method and got x=-1.1679 or closer to this
