Question

plz help..!!

Answer 1

\[(x+1/x =11 ) then find ( x^2+1/x^2)\]

Answer 2

@chmvijay

Answer 3

Whatchu mean?

Answer 4

X+1 divided by x=11???

Answer 5

x+ (1/x) mentioned in the que..!!

Answer 6

Can you take out the X?

Answer 7

it's X+(1/X)=11

So, In the equation can't you take out the X as common factor?

Answer 11

idk...

Answer 12

its ok no problem..thanks for trying..

Answer 13

I think you need to solve for x in the first one, then once you find that you plug that value into the second..

Answer 14

yaa but how.

Answer 15

yea.. that's what I was trying to do but that X+(1/X)=11 is weird

Answer 16

It's the same variable so I tried to factor it out but I don't think that's how it works...

Answer 17

Multiply both sides by x, since it's an equation I think you can do that..

Answer 18

It'll be \(\Large x^2+1=11x\)

Answer 19

Nvm seems complicated xD

Answer 20

Why multiply both sides, it'll make X^2 ... that will be one dirty sitaution

Answer 21

the question is not clear to me

Answer 22

its same as done by @DanielK16 but x is so weird

Answer 23

@myininaya can help us ~

Answer 24

I tried some equation calculators on the internet and they come out like quadratics with two answers...

Answer 25

i'm confused
is it (x+1)/x=11
or x+1/x=11?

Answer 26

second one the 1/x is a fraction

Answer 27

Is this calculus? with derivatives>?

Answer 28

so we have this:
\[x+\frac{1}{x}=11 ; x^2+\frac{1}{x^2}\]

Answer 29

@aayushi.somani

Answer 30

correct @ myininaya

Answer 31

my initial move is to square both sides of that equation first

Answer 32

oh yes that will work perfectly and beautifully

Answer 33

square both of sides of the equation x+1/x=11
to see magic

Answer 34

This is only a 2-step problem.

Answer 35

Woah~~

Answer 36

I saw magic

Answer 37

lol

Answer 38

@nirmalnema do you see?

Answer 39

nops..!

Answer 40

do you know how to square (x+1/x)?

Answer 41

\[(x+1/x)^2 =? \]

Answer 42

yaa.

Answer 43

Remember this means
\[(x+\frac{1}{x})(x+\frac{1}{x})\]
now multiply

Answer 44

ohh thanks i got it..its 119

Answer 45

yep

Answer 46

I thought to square both sides because the equation involved no items without squares
and what we wanted to find involved those items with squares

Answer 47

ok..!!

Answer 48

oops double negative
i hope you know what i mean

Answer 49

involved items without squares*

Answer 50

yaa ....
