How much is x (X-2) / x + 2 minus X-1?

How much is x (X-2) / x + 2 minus X-1?

X (X-2) of X + 2 minus (X-2) of X-1
=[(X+2)(X-2)]/[X(X-2)²] - [X(X-1)]/[X(X-2)²]
=(X²-4-X²+X)/[X(X-2)²]
=(X-4)/[X(X-2)²]
=(X-4)/(X³-4X²+4X)

X plus (one in x) equals 3, find x minus (one in x), and X is greater than one in X

(x-1/x)²
=(x+1/x)²-4
=3²-4
=5
x-1/x=√5

Three and three fourths minus x equals thirteen thirds minus seven fourths. Please give me the whole process

Three and three-quarters minus x is thirteen-thirds minus seven-quarters
15/4-x=13/3-7/4
x=15/4+7/4-13/3
x=11/2-13/3
x=33/6-26/6
x=7/6
