Issolvi -x(x-2)(x-5)

$$- x ( x - 2 ) ( x - 5 )$$

Evalwa

$$-x\left(x-5\right)\left(x-2\right)$$

Passi tas-Soluzzjonijiet

Uża l-propjetà distributtiva biex timmultiplika -x b'x-2.

$$\left(\left(-x\right)x-2\left(-x\right)\right)\left(x-5\right)$$

Immultiplika -2 u -1 biex tikseb 2.

$$\left(\left(-x\right)x+2x\right)\left(x-5\right)$$

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' \left(-x\right)x+2x b'kull terminu ta' x-5.

$$\left(-x\right)x^{2}-5\left(-x\right)x+2x^{2}-10x$$

Immultiplika -5 u -1 biex tikseb 5.

$$\left(-x\right)x^{2}+5xx+2x^{2}-10x$$

Immultiplika x u x biex tikseb x^{2}.

$$\left(-x\right)x^{2}+5x^{2}+2x^{2}-10x$$

Ikkombina 5x^{2} u 2x^{2} biex tikseb 7x^{2}.

$$\left(-x\right)x^{2}+7x^{2}-10x$$

Biex timmultiplika l-qawwa tal-istess bażi, żid l-esponenti tagħhom. Żid 1 u 2 biex tikseb 3.

$$-x^{3}+7x^{2}-10x$$

Espandi

$$-\left(x^{3}-7x^{2}+10x\right)$$

Passi tas-Soluzzjonijiet

Uża l-propjetà distributtiva biex timmultiplika -x b'x-2.

$$\left(\left(-x\right)x-2\left(-x\right)\right)\left(x-5\right)$$

Immultiplika -2 u -1 biex tikseb 2.

$$\left(\left(-x\right)x+2x\right)\left(x-5\right)$$

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' \left(-x\right)x+2x b'kull terminu ta' x-5.

$$\left(-x\right)x^{2}-5\left(-x\right)x+2x^{2}-10x$$

Immultiplika -5 u -1 biex tikseb 5.

$$\left(-x\right)x^{2}+5xx+2x^{2}-10x$$

Immultiplika x u x biex tikseb x^{2}.

$$\left(-x\right)x^{2}+5x^{2}+2x^{2}-10x$$

Ikkombina 5x^{2} u 2x^{2} biex tikseb 7x^{2}.

$$\left(-x\right)x^{2}+7x^{2}-10x$$
