2 / x + 2 - (1) / X-2 = 0 solve the equation and check (7 / x ^ 2 + x) + (3 / x ^ 2-x) = (6 / x ^ 2-1)

2 / x + 2 - (1) / X-2 = 0 solve the equation and check (7 / x ^ 2 + x) + (3 / x ^ 2-x) = (6 / x ^ 2-1)

1. Multiply both sides by (x + 2) (X-2)
2(x-2)-(x+2)=0
2x-4-x-2=0
∴x=6
Test: x = 6 is the solution of the equation
The solution of the equation is x = 6
2. Multiply both sides by X (x + 1) (x-1)
7(x-1)+3(x+1)=6x
7x-7+3x+3=6x
4x=4
x=1
Test: x = 1 is an increasing root
The equation has no solution
