Issolvi fm^2-14m-15=0

$$f m ^ { 2 } - 14 m - 15 = 0$$

Solvi għal f

$$f=\frac{14m+15}{m^{2}}$$

$$m\neq 0$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Żid 14m maż-żewġ naħat. Xi ħaġa plus żero jirriżulta f'dan in-numru stess.

$$fm^{2}-15=14m$$

Żid 15 maż-żewġ naħat.

$$fm^{2}=14m+15$$

L-ekwazzjoni hija f'forma standard.

$$m^{2}f=14m+15$$

Iddividi ż-żewġ naħat b'm^{2}.

$$\frac{m^{2}f}{m^{2}}=\frac{14m+15}{m^{2}}$$

Meta tiddividi b'm^{2} titneħħa l-multiplikazzjoni b'm^{2}.

$$f=\frac{14m+15}{m^{2}}$$

Solvi għal m (complex solution)

$$\left\{\begin{matrix}m=\frac{\sqrt{15f+49}+7}{f}\text{; }m=\frac{-\sqrt{15f+49}+7}{f}\text{, }&f\neq 0\\m=-\frac{15}{14}\text{, }&f=0\end{matrix}\right.$$

Solvi għal m

$$\left\{\begin{matrix}m=\frac{\sqrt{15f+49}+7}{f}\text{; }m=\frac{-\sqrt{15f+49}+7}{f}\text{, }&f\neq 0\text{ and }f\geq -\frac{49}{15}\\m=-\frac{15}{14}\text{, }&f=0\end{matrix}\right.$$
