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

Delite \frac{a^{2}-a-12}{2a^{2}+a} s/z \frac{16-a^{2}}{2a^{2}+9a+4} tako, da pomnožite \frac{a^{2}-a-12}{2a^{2}+a} z obratno vrednostjo \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)}

Faktorizirajte izraze, ki še niso faktorizirani.

\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)}

Ekstrahirajte znak minus v 4+a.

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

Okrajšaj \left(a-4\right)\left(-a-4\right)\left(2a+1\right) v števcu in imenovalcu.

\frac{-a-3}{a}
