Issolvi (1-lambda)(-1-lambda)(2-lambda)=

$$( 1 - \lambda ) ( - 1 - \lambda ) ( 2 - \lambda ) =$$

Evalwa

$$\left(2-\lambda \right)\left(\lambda ^{2}-1\right)$$

Passi tas-Soluzzjonijiet

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 1-\lambda b'kull terminu ta' -1-\lambda .

$$\left(-1-\lambda +\lambda +\lambda ^{2}\right)\left(2-\lambda \right)$$

Ikkombina -\lambda u \lambda biex tikseb 0.

$$\left(-1+\lambda ^{2}\right)\left(2-\lambda \right)$$

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' -1+\lambda ^{2} b'kull terminu ta' 2-\lambda .

$$-2+\lambda +2\lambda ^{2}-\lambda ^{3}$$

Espandi
