Question

5/x-2 + 3/x+2 = 20/ x2-4

me ajudem pfvv 

Answer 1

5 /x - 2 + 3 / x + 2 = 20 /( x + 2 )•(x - 2)
5( x + 2 ) + 3( x - 2 ) = 20
------------------------------------------------------------
(x +2)•(x -2)

5( x + 2 ) + 3 ( x - 2 ) = 20
5x + 10 + 3x - 6 = 20
8x + 4 = 20
8x = 20 - 4
8x = 16
x = 16 / 8
x = 2
