Evalwa

$$\frac{13x}{3}-\frac{14}{9}$$

Passi tas-Soluzzjonijiet

Ikkombina -x^{2} u -x^{2} biex tikseb -2x^{2}.

$$\frac{4}{9}-2x^{2}-1+2x+2x^{2}+\frac{7}{3}x-1$$

Naqqas 1 minn \frac{4}{9} biex tikseb -\frac{5}{9}.

$$-\frac{5}{9}-2x^{2}+2x+2x^{2}+\frac{7}{3}x-1$$

Ikkombina -2x^{2} u 2x^{2} biex tikseb 0.

$$-\frac{5}{9}+2x+\frac{7}{3}x-1$$

Ikkombina 2x u \frac{7}{3}x biex tikseb \frac{13}{3}x.

$$-\frac{5}{9}+\frac{13}{3}x-1$$

Naqqas 1 minn -\frac{5}{9} biex tikseb -\frac{14}{9}.

$$-\frac{14}{9}+\frac{13}{3}x$$
