@Shavi Masee ?? hoping u know

I think u do simplify x+1/x which equals x^2+1/x. Then you sub in root 3+2 and then simplify

sorry how does x+1/x become x^2+1/x???

X has the denominator of 1. So you times the top and bottom by x to make both denominators x.

Sub in x= root3 +2 into x+1/x

I think u do simplify x+1/x which equals x^2+1/x. Then you sub in root 3+2 and then simplify

I dont think thats necessary, i think u can immediately sub
bc then since its 1/x itll become 1/(root3 +2) which ull have to rationalise
so (assuming) ((root3 +2)^2 +1)/(root3 +2) is different from (root3 +2) + 1/(root3 +2)

LMAO I DID THAT THE OTHER DAY
there are two dif ways, you can work out the what that equation is, or you can sub in. I subbed in




atleast i think that's the reasonnn....

@Socialism

Also don’t u have to make the denominator the same so u would have to times the other fraction by root 3 +2

IKR THE NEXT QUESTION WAS WORSE THOUGH, IT TOOK ME 3 TRIES TO DO THAT
and then c was bassically a^2

thanks @jane1820 @Study to success @Shavi Masee

 

[Socialism]

anyway gn yall thanks

Oh yes yes ill tell u what i did wrong
i immediately did that root3 +2 is over -1 without actually multiplying by -1
so it would be
-(root3 +2)/-1 = -root3 -2/-1

In the first image how is it 4 root 3 +12+1 isn’t it 3+4 root 3 +4+1 which equals 8+4 root 3

Oops i multiplied 3 and 4
