Explicación paso a paso:
a.) 3 • (a + d) = 3a + 3d
b.) b • (3d – f) = 3bd - bf
c.) 2b • ( l + 3t – 8b) = 2bl + 6bt - 16[tex]b^{2}[/tex]
d.) 5t • ( 8d – 2r + [tex]d^{3}[/tex]) = 40dt - 10rt + 5[tex]d^{3}[/tex]t
e.) (2 + f) • (g + 3h) = 2•(g + 3h) + f•(g + 3h)
= 2g + 6h + fg + 3fh
f.) (r + 5t) • (k – g) = r•(k - g) + 5t•(k - g)
= rk - rg + 5kt - 5gt
g.) (m – n) • (ñ – p + 1) = m•(ñ – p + 1) - ñ•(ñ – p + 1)
= mñ - mp + m - ñ2 + ñp - ñ
h.) [tex]t^{2}[/tex] • ( 5d – 2l + 11 + [tex]t^{2}[/tex]) = 5d[tex]t^{2}[/tex] - 2l[tex]t^{2}[/tex] + 11[tex]t^{2}[/tex] + [tex]t^{4}[/tex]
