Find common denominator, subtract, and cross multiply to give the quadratic equation x^2-5x+6=0, or (x-3)(x-3)=0. However, check the two solutions x=2 or x=3 by substituting into the original equation. \(One\) of them gives a zero for denominator, hence is not a solution.

yes - the one that is not a solution is called extraneous.

  • anonymous
So I'm correct?
anonymous

@mathmate @welshfella
anonymous
  • anonymous
only 3 is a solution... I was wrong; a bit!
anonymous
  • anonymous
So, can you tell me which one is correct? @welshfella @mathmate

I'm lost!!!

workout:

  • anonymous
now plugging 2 into the original equation leads to infinity - infinity; which is absurd. but 3 gives a correct solution. check for it in the same way as for 2
welshfella
  • welshfella
there's an error in your last line multiplying through by (x-2)(x+2) gives (x-2)(x+2) on right hand side

@KittyT You have to do some work too! lol Read through my response and do some checking, and you will find your answer AND also understand why. OR read the last posts of @wrik003 to find the answer! Good luck!
welshfella
  • welshfella
it should be 5(x + 2) - 20 = x^2 - 4
anonymous
  • anonymous
I got 2 solutions....
welshfella
  • welshfella
what are they/
anonymous
  • anonymous
x=3 and x=2
anonymous
  • anonymous
u are stating something as exact as mine @welshfella. the only difference being that u have cross-multiplied x^2 -4 with 1! Hope u get it!
anonymous
  • anonymous
@KittyT check my 2nd last post & u shall find the answer
anonymous
  • anonymous
is it your workout?
anonymous
  • anonymous
I think there's one solution which is x=3
anonymous
  • anonymous
yes... whose else's workout could it be? my local time right now is 23:42! how do u suppose I'll get external; help?!
anonymous
  • anonymous
So it's right?
anonymous
  • anonymous
yes... my workout is correct... as verified my @mathmate.
anonymous
  • anonymous
So my final answer is 1 solution only!
anonymous
  • anonymous
yes... correct
