Issolvi P(x)+P(x-1)=2x^2-4x+2

$$P ( x ) + P ( x - 1 ) = 2 x ^ { 2 } - 4 x + 2$$

Solvi għal P

$$P=\frac{2\left(x-1\right)^{2}}{2x-1}$$

$$x\neq \frac{1}{2}$$

Passi biex Issolvi l-Ekwazzjoni Lineari

Uża l-propjetà distributtiva biex timmultiplika P b'x-1.

$$Px+Px-P=2x^{2}-4x+2$$

Ikkombina Px u Px biex tikseb 2Px.

$$2Px-P=2x^{2}-4x+2$$

Ikkombina t-termini kollha li fihom P.

$$\left(2x-1\right)P=2x^{2}-4x+2$$

Iddividi ż-żewġ naħat b'2x-1.

$$\frac{\left(2x-1\right)P}{2x-1}=\frac{2\left(x-1\right)^{2}}{2x-1}$$

Meta tiddividi b'2x-1 titneħħa l-multiplikazzjoni b'2x-1.

$$P=\frac{2\left(x-1\right)^{2}}{2x-1}$$

Solvi għal x (complex solution)

$$x=\frac{-\sqrt{P\left(P+2\right)}+P+2}{2}$$

$$x=\frac{\sqrt{P\left(P+2\right)}+P+2}{2}$$

Solvi għal x

$$x=\frac{-\sqrt{P\left(P+2\right)}+P+2}{2}$$

$$x=\frac{\sqrt{P\left(P+2\right)}+P+2}{2}\text{, }P\leq -2\text{ or }P\geq 0$$
