Question

Alguém pode corrigir, por favor. Grata

Answer 1

$a)\\3x*(3x^{2}-2x+3)\\9x^{3}-6x^{2}+9x$

$b)\\4xy*(3x^{2}-y)\\12x^{3}y-4xy^{2}$

$c)\\-3a^{3}*(a^{4}-2a+1)\\-3a^{7}+6a^{4}-3a^{3}$

$d)\\5a^{2}b^{3}*(4a^{3}-2b^{2})\\20a^{5}b^{3}-10a^{2}b^{5}$

$e)\\(2x-1)*(3x^{2}+4x)\\6x^{3}+8x^{2} -3x^{2}-4x\\6x^{3}+5x^{2}-4x$

Boa noite =)
