-First, use properly parentheses!x = - 3/7, answer!-Hint: multiply both sides by x^2 - 4 and realize that x^2 - 4 = (x-2)(x+2)-Please use brackets, this can be interpreted in numerous different ways.......
Solve for x, 3 / x² - 4 = 2 / x + 2 + 5 / x - 2


how is this done?

-
First, use properly parentheses!

3/(x² - 4) = 2/(x + 2) + 5/(x - 2)

lcd = x^2 - 4

3 = 2*(x - 2) + 5*(x + 2)

2*x - 4 + 5*x + 10 = 3

7*x = - 3

x = - 3/7, answer!

-
Hint: multiply both sides by x^2 - 4 and realize that x^2 - 4 = (x-2)(x+2)

Please use brackets, this can be interpreted in numerous different ways.
