Passi tas-Soluzzjonijiet

Uża l-propjetà distributtiva biex timmultiplika 8 b'x+3.

$$\left(8x+24\right)\left(x+4\right)-x\left(x+2\right)-5$$

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 8x+24 b'kull terminu ta' x+4.

$$8x^{2}+32x+24x+96-x\left(x+2\right)-5$$

Ikkombina 32x u 24x biex tikseb 56x.

$$8x^{2}+56x+96-x\left(x+2\right)-5$$

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

$$8x^{2}+56x+96-\left(x^{2}+2x\right)-5$$

Biex issib l-oppost ta' x^{2}+2x, sib l-oppost ta' kull terminu.

$$8x^{2}+56x+96-x^{2}-2x-5$$
