Question 626493: Solve. Select the correct choice below
A) The solution is x=___
B) There is no solution

You can put this solution on YOUR website! Select the correct choice below
A) The solution is x=___
B) There is no solution
x/x+8 - 8/x-8 = x^2+64/x^2-64
----
Multiply thru by x^2-64 which equals (x+8)(x-8), to get:
---
x(x-8) - 8(x+8) = x^2+64
-----
x^2-8x - 8x -64 = x^2+64
---
-16x = 128
x = 8
---
But x cannot be 8 because that would
cause 2 denominators of the original
problem to be zero.
---
Conclusion: No solution
