hba 3 years ago Center of the circle represented by the equation 5x^2+5y^2+24x+36y+10=0

1. waterineyes

Use Completion Of Square Method..

2. hba

What ?

3. waterineyes

Nothing.. I said use your method to solve it..

4. hba

Which method dude ?

5. hba

6. waterineyes

There you have open the square, here you will close the square.. I mean, write that in the form of square.. $$(....)^2$$

7. hba

@waterineyes ??

8. hba

Let me try :(

9. waterineyes

Can I give you some other example??

10. waterineyes

Firstly make the coefficient of $$x^2$$ and $$y^2$$ as 1..

11. waterineyes

Try first..

12. hba

I am comparing it let me do it dont answer

13. hba

Or i will keeeel you.

14. hba

@waterineyes (-g,-f)=(-12/5,-18/5)

15. waterineyes

Wait, let me check..

16. waterineyes

And you are right..

17. hba

Thanks A lot :)

18. hba

What will be the radius of this equation ? @waterineyes

19. hba

@hartnn Is it r=root(g^2+f^2-c)=0

20. waterineyes

Now, solve for all the constants there..

21. hba

How am i going to survive without a calculator ?

22. waterineyes

$(x+\frac{12}{5})^2 + (y+\frac{18}{5})^2 - (\frac{12}{5})^2 - (\frac{18}{5})^2 +10 = 0$

23. waterineyes

Just solve the constant terms here..

24. hartnn

r=root(g^2+f^2-c) is the direct formula....if u need to show work, follow water.

25. hba

I do not need to show work lol,i just need to get the answer right :D

26. waterineyes

What is c here?? 10 @hartnn

27. waterineyes

Simple, then follow @hartnn Ha ha ha..

28. hba

I am using that formula lol :D

29. hba

And c = 10/5

30. waterineyes

And I am not typing.. Ha ha ha ha...

31. hba

@waterineyes Common sense is not so common :)

32. waterineyes

See, @hartnn has used there c = 10. Ha ha ha..

33. hartnn

c=10 here.

34. waterineyes

So, we don't divide it here by 5 to c??

35. hba

Haha @hartnn you are wrong :(

36. hartnn

ok, my bad....i thot of different general equation....

37. hba

38. hba

@hartnn ok fine.

39. waterineyes

hartnn is taking time to think if it was wrong or right..

40. hba

@waterineyes You are confusing people today lol

41. waterineyes

So, c = 2.. @hba now you cannot refuse here.. Ha ha ha..

42. hartnn

lets move on guys :P

43. waterineyes

I am not confusing anybody, but confirming..

44. hba

Yeah lol

45. hba

Now as hartnn said move on :)

46. waterineyes

Otherwise, I will explode your fuse.,. ha ha ha..

47. waterineyes

How can I?? I am sitting on my chair.. Ha ha ha..

48. hba

From the question lol :D

49. hba

I thought i deserved a medal here :(

50. waterineyes

Okay, this looks fine..

51. waterineyes

@hartnn give your medal to @hba

52. waterineyes

Okay, I give you now..

53. waterineyes

I wish I could have more medals.. So that I can give them to me only.. Ha ha ha ha..
