\frac{x^{2}}{x-1}-x\leq 1
Resteu x en tots dos costats.
\frac{x^{2}}{x-1}-\frac{x\left(x-1\right)}{x-1}\leq 1
Per afegir o restar les expressions, amplieu-les perquè els denominadors coincideixin. Multipliqueu x per \frac{x-1}{x-1}.
\frac{x^{2}-x\left(x-1\right)}{x-1}\leq 1
Com que \frac{x^{2}}{x-1} i \frac{x\left(x-1\right)}{x-1} tenen el mateix denominador, resteu-los mitjançant la subtracció dels seus numeradors.
\frac{x^{2}-x^{2}+x}{x-1}\leq 1
Feu les multiplicacions a x^{2}-x\left(x-1\right).
\frac{x}{x-1}\leq 1
Combineu els termes similars de x^{2}-x^{2}+x.
x-1>0 x-1<0
Denominator x-1 cannot be zero since division by zero is not defined. There are two cases.
x>1
Consider the case when x-1 is positive. Move -1 to the right hand side.
x\leq x-1
The initial inequality does not change the direction when multiplied by x-1 for x-1>0.
x-x\leq -1
Move the terms containing x to the left hand side and all other terms to the right hand side.
0\leq -1
Combineu els termes iguals.
x\in \emptyset
Consider condition x>1 specified above.
x<1
Now consider the case when x-1 is negative. Move -1 to the right hand side.
x\geq x-1
The initial inequality changes the direction when multiplied by x-1 for x-1<0.
x-x\geq -1
Move the terms containing x to the left hand side and all other terms to the right hand side.
0\geq -1
Combineu els termes iguals.
x<1
Consider condition x<1 specified above.
x<1
