simplify (x^2-1/x)/(x^2+1)

simplify

\frac{x ^{2} - \frac{1}{x}}{x ^{2} + 1}

\frac{x ^{3} - 1}{x ( x ^{2} + 1 )}

Solution steps

\frac{x ^{2} - \frac{1}{x}}{x ^{2} + 1}

Join

x^{2} - \frac{1}{x} : \frac{x ^{3} - 1}{x}

= \frac{\frac{x ^{3} - 1}{x}}{x ^{2} + 1}

Apply the fraction rule:

\frac{\frac{a}{b}}{c} = \frac{a}{b \cdot c}

= \frac{x ^{3} - 1}{x ( x ^{2} + 1 )}

\frac{21 x ^{2} y ^{3}}{7 x ^{2} y ^{2}}

\frac{( 18 x ^{6} y ^{2} z ^{5} )}{( 6 x ^{3} y z ^{2} )}

\frac{1}{2} - \frac{4}{3}

f (x) + 2

1.8 y - 9.3 y - 6.3 y
