Question

Eu quero minha resposta (a-1)³

Answer 1

$\large\bm{\left(a - 1\right)^{3} } \\ \\ \large\bm{} {a}^{3} - 3 {a}^{2} \times 1 + 3a \times {1}^{2} - {1}^{3} \\ \large\bm{} {a}^{3} - {3a}^{2} + 3a \times 1 - 1 \\ \large\bm{}\bm{\large\boxed{\boxed{  { \large \bm{ {a}^{3} - {3a}^{2} + 3a - 1 }}}}}$

${\large\boxed{\boxed{  { \large \bm{ Bons~Estudos} }}}}$
