1. anonymous

$(x+1/x =11 ) then find ( x^2+1/x^2)$

2. anonymous

@chmvijay

3. anonymous

Whatchu mean?

4. anonymous

X+1 divided by x=11???

5. anonymous

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

6. anonymous

Can you take out the X?

7. anonymous

it's X+(1/X)=11 So, In the equation can't you take out the X as common factor?

11. anonymous

idk...

12. anonymous

its ok no problem..thanks for trying..

13. Luigi0210

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

14. anonymous

yaa but how.

15. anonymous

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

16. anonymous

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

17. Luigi0210

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

18. Luigi0210

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

19. Luigi0210

Nvm seems complicated xD

20. anonymous

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

21. anonymous

the question is not clear to me

22. anonymous

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

23. Luigi0210

@myininaya can help us ~

24. anonymous

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

25. myininaya

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

26. anonymous

second one the 1/x is a fraction

27. anonymous

28. anonymous

Is this calculus? with derivatives>?

29. myininaya

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

30. anonymous

@aayushi.somani

31. anonymous

correct @ myininaya

32. myininaya

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

33. myininaya

oh yes that will work perfectly and beautifully

34. myininaya

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

35. myininaya

This is only a 2-step problem.

36. anonymous

Woah~~

37. anonymous

I saw magic

38. myininaya

lol

39. myininaya

@nirmalnema do you see?

40. anonymous

nops..!

41. myininaya

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

42. myininaya

$(x+1/x)^2 =?$

43. anonymous

yaa.

44. myininaya

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

45. anonymous

ohh thanks i got it..its 119

46. myininaya

yep

47. myininaya

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

48. anonymous

ok..!!

49. myininaya

oops double negative i hope you know what i mean

50. myininaya

involved items without squares*

51. anonymous

yaa ....
