Koraci za rješenje

Izračunajte 10 stepen od -12 i dobijte \frac{1}{1000000000000}.

$$z^{2}-25\times \frac{1}{1000000000000}+16\times 10^{-12}$$

Pomnožite 25 i \frac{1}{1000000000000} da biste dobili \frac{1}{40000000000}.

$$z^{2}-\frac{1}{40000000000}+16\times 10^{-12}$$

Izračunajte 10 stepen od -12 i dobijte \frac{1}{1000000000000}.

$$z^{2}-\frac{1}{40000000000}+16\times \frac{1}{1000000000000}$$

Pomnožite 16 i \frac{1}{1000000000000} da biste dobili \frac{1}{62500000000}.

$$z^{2}-\frac{1}{40000000000}+\frac{1}{62500000000}$$

Saberite -\frac{1}{40000000000} i \frac{1}{62500000000} da biste dobili -\frac{9}{1000000000000}.

$$z^{2}-\frac{9}{1000000000000}$$

Faktor

$$\frac{\left(1000000z-3\right)\left(1000000z+3\right)}{1000000000000}$$
