Issolvi (5n-4/5)(5n-1/5)

$$( 5 n - \frac { 4 } { 5 } ) ( 5 n - \frac { 1 } { 5 } )$$

Evalwa

$$25n^{2}-5n+\frac{4}{25}$$

Passi tas-Soluzzjonijiet

Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 5n-\frac{4}{5} b'kull terminu ta' 5n-\frac{1}{5}.

$$25n^{2}+5n\left(-\frac{1}{5}\right)-\frac{4}{5}\times 5n-\frac{4}{5}\left(-\frac{1}{5}\right)$$

Annulla 5 u 5.

$$25n^{2}-n-\frac{4}{5}\times 5n-\frac{4}{5}\left(-\frac{1}{5}\right)$$

Annulla 5 u 5.

$$25n^{2}-n-4n-\frac{4}{5}\left(-\frac{1}{5}\right)$$

Ikkombina -n u -4n biex tikseb -5n.

$$25n^{2}-5n-\frac{4}{5}\left(-\frac{1}{5}\right)$$

Immultiplika -\frac{4}{5} b'-\frac{1}{5} billi timmultiplika n-numeratur bin-numeratur u d-denominatur bid-denominatur.

$$25n^{2}-5n+\frac{-4\left(-1\right)}{5\times 5}$$

Agħmel il-multiplikazzjonijiet fil-frazzjoni \frac{-4\left(-1\right)}{5\times 5}.

$$25n^{2}-5n+\frac{4}{25}$$
