When the value of K is what, solving the fractional equation 1 / (x + 2) - K / (X-2) = 1-4x / (x ^ 2-4) will produce increasing roots

When the value of K is what, solving the fractional equation 1 / (x + 2) - K / (X-2) = 1-4x / (x ^ 2-4) will produce increasing roots

Multiply by (x + 2) (X-2)
(x-2)-k(x+2)=(x+2)(x-2)-4x
The increasing root of the fractional equation is that the denominator is 0
(x+2)(x-2)=0
x=-2,x=2
X = - 2, substituting (X-2) - K (x + 2) = (x + 2) (X-2) - 4x
-4-0 = 0 + 8, not true
X = 2, substituting (X-2) - K (x + 2) = (x + 2) (X-2) - 4x
0-4k=0-8
k=2
