Lahenda x^2+5x+6=56cm^2

$$x ^ { 2 } + 5 x + 6 = 56 cm ^ { 2 }$$

Lahendage ja leidke c (complex solution)

$$\left\{\begin{matrix}c=\frac{\left(x+2\right)\left(x+3\right)}{56m^{2}}\text{, }&m\neq 0\\c\in \mathrm{C}\text{, }&\left(x=-2\text{ or }x=-3\right)\text{ and }m=0\end{matrix}\right,$$

Juhised lineaarvõrrandi lahendamiseks

Vahetage pooled nii, et kõik muutuvad liikmed asuksid vasakul.

$$56cm^{2}=x^{2}+5x+6$$

Võrrand on standardkujul.

$$56m^{2}c=x^{2}+5x+6$$

Jagage mõlemad pooled 56m^{2}-ga.

$$\frac{56m^{2}c}{56m^{2}}=\frac{\left(x+2\right)\left(x+3\right)}{56m^{2}}$$

56m^{2}-ga jagamine võtab 56m^{2}-ga korrutamise tagasi.

$$c=\frac{\left(x+2\right)\left(x+3\right)}{56m^{2}}$$

Lahendage ja leidke c

$$\left\{\begin{matrix}c=\frac{\left(x+2\right)\left(x+3\right)}{56m^{2}}\text{, }&m\neq 0\\c\in \mathrm{R}\text{, }&\left(x=-2\text{ or }x=-3\right)\text{ and }m=0\end{matrix}\right,$$
