solve for x

Answer 1

find the positive root

Answer 2

Newton's method

Answer 3

not Galileo's ?

Answer 4

uhm can I use Wolfram Alpha? :DD

Answer 5

laughing out loud

Answer 6

I am trying to figure out an easy way to answer this

Answer 7

by Newton's method i got \[x \approx 0.7548\]

Answer 8

Only one answer?

Answer 9

sure you did
by wolfram's method I got x = 0.754877666246693

Answer 10

one real and 4 complex

Answer 11

teach us, musss

Answer 12

teach us, oh newton incarnatete

Answer 13

Answer 14

let x^5+x-1=f(x)
if x=0 f(0)=-1
if x=1 f(1)=1
f(0).f(1)=negative
that means we have root in (0,1)

Answer 15

Yep, either newton's method or graphing. You can't solve for x algebraically

Answer 16

i used numerical method :)

Answer 17

laughing out loud i saw it done algebraically
