Question

(x/x-2)-(x/x+2)=1

Answer 1

I think something wrong in the question .... please correct it. Use "Equation" button to get the equation in good shape

Answer 2

do you think there are infinetly many solutions or none at all

Answer 3

Simplify the left hand side will give you
(4x)/(x^2 - 4) = 1
[(4x)/(x^2 - 4) ]- 1 = 0
(x^2 - 4x - 4)/(x^2 - 4) = 0
=> x^2 -4x -4 = 0 which you can solve by using the quadratic formula

Answer 4

show me how to use it pls

Answer 5

roots are
\[-2 (\sqrt(2) -1)and 2 ( \sqrt(2) +1)\]

Answer 6

kynosis is this the answer

Answer 7

Kynosis, you know how to type out the quadratic formula nicely, please show to Tru769150

Answer 8

I don't know how to type it here, sorry Tru

Answer 9

but is what kynosis posted the answer

Answer 10

\[ x=\frac{-b \pm \sqrt {b^2-4ac}}{2a}, \]
which
a is the coefficient of the x^2 term
b is the coefficient of the x^1 term
c is the coefficient of the x^0 term

Answer 11

so can you show me how i write this in there
x^2-4x-4=0

Answer 12

Find the common denominator which is (x-2)(x+2)

then the equation is \[x^2 -4x -4 = 0\]

Answer 13

\[ x=\frac{4 \pm \sqrt {4^2+4(4)}}{2}, \]

Answer 14

simplify and you have the same answer

Answer 15

so it would be 4+or -4squrt of 2/2
