Question

Any idea?

Answer 1

@mathmate

Hello. This one is tough one for me! PLease help

Answer 2

@wrik003

Answer 3

2 solutions... x = 3 and x = 2... do u need a detailed explanation as before?

Answer 4

Oh yes please! If anyone who have different idea please let me know

Answer 5

hold on a minute

Answer 6

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.

Answer 7

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

Answer 8

So I'm correct?

Answer 9

@mathmate
@welshfella

Answer 10

only 3 is a solution... I was wrong; a bit!

Answer 11

So, can you tell me which one is correct? @welshfella @mathmate

Answer 12

I'm lost!!!

Answer 13

workout:

Answer 14

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

Answer 15

there's an error in your last line
multiplying through by (x-2)(x+2) gives (x-2)(x+2) on right hand side

Answer 16

@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!

Answer 17

it should be

5(x + 2) - 20 = x^2 - 4

Answer 18

I got 2 solutions....

Answer 19

what are they/

Answer 20

x=3 and x=2

Answer 21

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!

Answer 22

@KittyT check my 2nd last post & u shall find the answer

Answer 23

is it your workout?

Answer 24

I think there's one solution which is x=3

Answer 25

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?!

Answer 26

So it's right?

Answer 27

yes... my workout is correct... as verified my @mathmate.

Answer 28

So my final answer is 1 solution only!

Answer 29

yes... correct
