Esercizio
$\frac{x^5}{9-x^2}$
Soluzione passo-passo
1
Dividere $x^5$ per $9-x^2$
$\begin{array}{l}\phantom{-x^{2}+9;}{-x^{3}\phantom{-;x^n}-9x\phantom{;}\phantom{-;x^n}}\\-x^{2}+9\overline{\smash{)}\phantom{;}x^{5}\phantom{-;x^n}\phantom{-;x^n}\phantom{-;x^n}\phantom{-;x^n}\phantom{-;x^n}}\\\phantom{-x^{2}+9;}\underline{-x^{5}\phantom{-;x^n}+9x^{3}\phantom{-;x^n}\phantom{-;x^n}\phantom{-;x^n}}\\\phantom{-x^{5}+9x^{3};}\phantom{;}9x^{3}\phantom{-;x^n}\phantom{-;x^n}\phantom{-;x^n}\\\phantom{-x^{2}+9-;x^n;}\underline{-9x^{3}\phantom{-;x^n}+81x\phantom{;}\phantom{-;x^n}}\\\phantom{;-9x^{3}+81x\phantom{;}-;x^n;}\phantom{;}81x\phantom{;}\phantom{-;x^n}\\\end{array}$
$-x^{3}-9x+\frac{81x}{9-x^2}$
Risposta finale al problema
$-x^{3}-9x+\frac{81x}{9-x^2}$
