Issolvi d=(t+08)(t+12)

$$d = ( t + 08 ) ( t + 12 )$$

Solvi għal d

$$d=t\left(t+12\right)$$

Passi tas-Soluzzjonijiet

Immultiplika 0 u 8 biex tikseb 0.

$$d=\left(t+0\right)\left(t+12\right)$$

Xi ħaġa plus żero jirriżulta f'dan in-numru stess.

$$d=t\left(t+12\right)$$

Uża l-propjetà distributtiva biex timmultiplika t b't+12.

$$d=t^{2}+12t$$

Solvi għal t

$$t=-\sqrt{d+36}-6$$

$$t=\sqrt{d+36}-6\text{, }d\geq -36$$
