Passi tas-Soluzzjonijiet

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 2x+3 b'kull terminu ta' 6x+2.

$$12x^{2}+4x+18x+6-6x\left(2x+13\right)+8\left(7x+2\right)$$

Ikkombina 4x u 18x biex tikseb 22x.

$$12x^{2}+22x+6-6x\left(2x+13\right)+8\left(7x+2\right)$$

Uża l-propjetà distributtiva biex timmultiplika 8 b'7x+2.

$$12x^{2}+22x+6-6x\left(2x+13\right)+56x+16$$

Uża l-propjetà distributtiva biex timmultiplika -6x b'2x+13.

$$12x^{2}+22x+6-12x^{2}-78x+56x+16$$

Ikkombina 12x^{2} u -12x^{2} biex tikseb 0.

$$22x+6-78x+56x+16$$

Ikkombina 22x u -78x biex tikseb -56x.

$$-56x+6+56x+16$$

Ikkombina -56x u 56x biex tikseb 0.

$$6+16$$
