\left(10n+2\right)\left(4n-\frac{4}{5}\right)
Uża l-propjetà distributtiva biex timmultiplika 2 b'5n+1.
40n^{2}+10n\left(-\frac{4}{5}\right)+8n+2\left(-\frac{4}{5}\right)
Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 10n+2 b'kull terminu ta' 4n-\frac{4}{5}.
40n^{2}+\frac{10\left(-4\right)}{5}n+8n+2\left(-\frac{4}{5}\right)
Esprimi 10\left(-\frac{4}{5}\right) bħala frazzjoni waħda.
40n^{2}+\frac{-40}{5}n+8n+2\left(-\frac{4}{5}\right)
Immultiplika 10 u -4 biex tikseb -40.
40n^{2}-8n+8n+2\left(-\frac{4}{5}\right)
Iddividi -40 b'5 biex tikseb-8.
40n^{2}+2\left(-\frac{4}{5}\right)
Ikkombina -8n u 8n biex tikseb 0.
40n^{2}+\frac{2\left(-4\right)}{5}
Esprimi 2\left(-\frac{4}{5}\right) bħala frazzjoni waħda.
40n^{2}+\frac{-8}{5}
Immultiplika 2 u -4 biex tikseb -8.
40n^{2}-\frac{8}{5}
Frazzjoni \frac{-8}{5} tista' tinkiteb mill-ġdid bħala -\frac{8}{5} bl-estrazzjoni tas-sinjal negattiv.
\left(10n+2\right)\left(4n-\frac{4}{5}\right)
Uża l-propjetà distributtiva biex timmultiplika 2 b'5n+1.
40n^{2}+10n\left(-\frac{4}{5}\right)+8n+2\left(-\frac{4}{5}\right)
Applika l-propjetà distributtiva billi timmultiplika kull terminu ta' 10n+2 b'kull terminu ta' 4n-\frac{4}{5}.

40n^{2}+\frac{-8}{5}
Immultiplika 2 u -4 biex tikseb -8.
40n^{2}-\frac{8}{5}
Frazzjoni \frac{-8}{5} tista' tinkiteb mill-ġdid bħala -\frac{8}{5} bl-estrazzjoni tas-sinjal negattiv.
