Szczegółowe wyjaśnienie:
pr*3p²r-(-rp)*(-2pr)+3*prprp-r²*4pp
3p³r²-2p²r²+3prprp-4p²r²
3p³r²-6p²r²+3prprp
3p³r²-6p²r²+3p³r²
6p³r²-6p²r²
6p²r²(p-1)
[tex]e) \ pr\cdot3p^{2}r - (-rp)\cdot(-2pr)+3\cdot prprp - r^{2}\cdot4pp =\\\\=3p^{3}r^{2}-2p^{2}r^{2} +3p^{3}r^{2} - 4p^{2}r^{2}=\\\\=6p^{3}r^{2}-6p^{2}r^{2}=6p^{2}r^{2}(p-1)[/tex]
