3(m²+n²+p²)
Объяснение:
3m(m+n-p)-3n(m-n-p)+3p(m-n+p) =
= 3(m (m+n-p) - n(m-n-p) + p(m-n+p)=
= 3(m² + mn - mp -mn + n² + np + mp - np + p²)=
=3(m²+n²+p²)
3m^2+3mn-3mp-3nm+3n^2+3np+3mp-3np+3p^2=3m^2+3n^2+3p^2
3(m²+n²+p²)
Объяснение:
3m(m+n-p)-3n(m-n-p)+3p(m-n+p) =
= 3(m (m+n-p) - n(m-n-p) + p(m-n+p)=
= 3(m² + mn - mp -mn + n² + np + mp - np + p²)=
=3(m²+n²+p²)
Объяснение:
3m^2+3mn-3mp-3nm+3n^2+3np+3mp-3np+3p^2=3m^2+3n^2+3p^2
