Riješi 6n9x^2+25y^2-54x+100y-44=0

$$6 n 9 x ^ { 2 } + 25 y ^ { 2 } - 54 x + 100 y - 44 = 0$$

Riješite za n_9 (complex solution)

$$\left\{\begin{matrix}n_{9}=-\frac{25y^{2}-54x+100y-44}{6x^{2}}\text{, }&x\neq 0\\n_{9}\in \mathrm{C}\text{, }&\left(y=\frac{2}{5}\text{ or }y=-\frac{22}{5}\right)\text{ and }x=0\end{matrix}\right,$$

Koraci za rješavanje linearne jednačine

Oduzmite 25y^{2} s obje strane. Bilo šta oduzeto od nule daje svoju negaciju.

$$6n_{9}x^{2}-54x+100y-44=-25y^{2}$$

Dodajte 54x na obje strane.

$$6n_{9}x^{2}+100y-44=-25y^{2}+54x$$

Oduzmite 100y s obje strane.

$$6n_{9}x^{2}-44=-25y^{2}+54x-100y$$

Dodajte 44 na obje strane.

$$6n_{9}x^{2}=-25y^{2}+54x-100y+44$$

Jednačina je u standardnom obliku.

$$6x^{2}n_{9}=54x-25y^{2}-100y+44$$

Podijelite obje strane s 6x^{2}.

$$\frac{6x^{2}n_{9}}{6x^{2}}=\frac{54x-25y^{2}-100y+44}{6x^{2}}$$

Dijelјenje sa 6x^{2} poništava množenje sa 6x^{2}.

$$n_{9}=\frac{54x-25y^{2}-100y+44}{6x^{2}}$$

Riješite za n_9
