Why don't you perform expansion?

[dapper gale]

change x-1 into (square x - 1)(square x+1)

no need for expansion

it will take u 10 yers

[sharp tartan]

I just couldn't solve it, I only found one root

[dapper gale]

ye

the only solution is x=1 ig

ah no

wait lemem try

[sharp tartan]

idk how to solve it xdd

no ideas

[sharp tartan]

its okaay

[gloomy shuttle]

[sharp tartan]

Your decision is so brilliant xd

[dapper gale]

wwait idk how to

really

get 0.04

[sharp tartan]

x-1=(√x-1)(√x+1)?

[dapper gale]

ye

[sharp tartan]

oh, yea

really xd

and you applied the grouping method to √x-1?

[dapper gale]

ye

[sharp tartan]

okay one moment

[dapper gale]

not sure what grouping method is..

[sharp tartan]

btw

will i need to multiply a bracket by a bracket in your last action?

[dapper gale]

wdym

[sharp tartan]

[dapper gale]
