Issolvi fx^2+y^2-2x-6y+5=0

$$f x ^ { 2 } + y ^ { 2 } - 2 x - 6 y + 5 = 0$$

Solvi għal f (complex solution)

$$\left\{\begin{matrix}f=-\frac{5-6y+y^{2}-2x}{x^{2}}\text{, }&x\neq 0\\f\in \mathrm{C}\text{, }&\left(y=5\text{ or }y=1\right)\text{ and }x=0\end{matrix}\right.$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Naqqas y^{2} miż-żewġ naħat. Xi ħaġa mnaqqsa minn żero tagħti numru negattiv.

$$fx^{2}-2x-6y+5=-y^{2}$$

Żid 2x maż-żewġ naħat.

$$fx^{2}-6y+5=-y^{2}+2x$$

Żid 6y maż-żewġ naħat.

$$fx^{2}+5=-y^{2}+2x+6y$$

Naqqas 5 miż-żewġ naħat.

$$fx^{2}=-y^{2}+2x+6y-5$$

L-ekwazzjoni hija f'forma standard.

$$x^{2}f=2x-y^{2}+6y-5$$

Iddividi ż-żewġ naħat b'x^{2}.

$$\frac{x^{2}f}{x^{2}}=\frac{2x-y^{2}+6y-5}{x^{2}}$$

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

$$f=\frac{2x-y^{2}+6y-5}{x^{2}}$$
