x(x-1)=1

Let f(x)=x((1)/(x-1)+(1)/(x)+(1)/(x+1)), x gt 1 . Then

Let f(x)=x((1)/(x-1)+(1)/(x)+(1)/(x+1)),xgt1 . Then _____

If f(x)=|{:(1,x,x+1),(2x,x(x-1),(x+1)x),(3x(x-1),x(x-1)(x-2),(x+1)x(x-1)):}| then

Solve (x)/(x-1) + (x+1)/(x) = 2 (1)/(2)

The function f(x)=(x-1)/(x+1), x ne -1 is

Solve : (x)/(x-1)+(x-1)/(x)=2(1)/(2) .

If f(x) =|(1, x, x+1),(2x, x(x-1), x(x+1)), (3x(x-1), 2(x-1)(x-2), x(x+1)(x-1))| then what is f(-1) +f(0) +f(1) equal to ?

If f(x) = |(1,x,x+1),(2x,x(x-1),x(x+1)),(3x(x-1),x(x-1)(x-2),x(x+1)(x-1))| , using properties of determinant, find f(2x) - f(x).
