Issolvi 2m(m-5)-(5-m)(m-6)

$$2 m ( m - 5 ) - ( 5 - m ) ( m - 6 )$$

Evalwa

$$3\left(m-5\right)\left(m-2\right)$$

Passi tas-Soluzzjonijiet

Uża l-propjetà distributtiva biex timmultiplika 2m b'm-5.

$$2m^{2}-10m-\left(5-m\right)\left(m-6\right)$$

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 5-m b'kull terminu ta' m-6.

$$2m^{2}-10m-\left(5m-30-m^{2}+6m\right)$$

Ikkombina 5m u 6m biex tikseb 11m.

$$2m^{2}-10m-\left(11m-30-m^{2}\right)$$

Biex issib l-oppost ta' 11m-30-m^{2}, sib l-oppost ta' kull terminu.

$$2m^{2}-10m-11m-\left(-30\right)-\left(-m^{2}\right)$$

L-oppost ta' -30 huwa 30.

$$2m^{2}-10m-11m+30-\left(-m^{2}\right)$$

L-oppost ta' -m^{2} huwa m^{2}.

$$2m^{2}-10m-11m+30+m^{2}$$

Ikkombina -10m u -11m biex tikseb -21m.

$$2m^{2}-21m+30+m^{2}$$

Ikkombina 2m^{2} u m^{2} biex tikseb 3m^{2}.

$$3m^{2}-21m+30$$

Espandi

$$3m^{2}-21m+30$$

$$2m^{2}-10m-\left(11m-30-m^{2}\right)$$

Biex issib l-oppost ta' 11m-30-m^{2}, sib l-oppost ta' kull terminu.

$$2m^{2}-10m-11m-\left(-30\right)-\left(-m^{2}\right)$$

L-oppost ta' -30 huwa 30.

$$2m^{2}-10m-11m+30-\left(-m^{2}\right)$$

L-oppost ta' -m^{2} huwa m^{2}.

$$2m^{2}-10m-11m+30+m^{2}$$

Ikkombina -10m u -11m biex tikseb -21m.

$$2m^{2}-21m+30+m^{2}$$

Ikkombina 2m^{2} u m^{2} biex tikseb 3m^{2}.

$$3m^{2}-21m+30$$
