\frac{\left(a^{2}-a-12\right)\left(2a^{2}+9a+4\right)}{\left(2a^{2}+a\right)\left(16-a^{2}\right)}

Dividi \frac{a^{2}-a-12}{2a^{2}+a} per\frac{16-a^{2}}{2a^{2}+9a+4} moltiplicando \frac{a^{2}-a-12}{2a^{2}+a} per il reciproco di \frac{16-a^{2}}{2a^{2}+9a+4}.

\frac{\left(a-4\right)\left(a+3\right)\left(a+4\right)\left(2a+1\right)}{a\left(a-4\right)\left(-a-4\right)\left(2a+1\right)}

Scomponi in fattori le espressioni che non sono già scomposte.

\frac{-\left(a-4\right)\left(-a-4\right)\left(a+3\right)\left(2a+1\right)}{a\left(a-4\right)\left(-a-4\right)\left(2a+1\right)}

Estrai il segno negativo in 4+a.

\frac{-\left(a+3\right)}{a}

Cancella \left(a-4\right)\left(-a-4\right)\left(2a+1\right) nel numeratore e nel denominatore.

\frac{-a-3}{a}
