--------------------------
2

Answer 1

Resposta:

$(18x {}^{2} - 12x)(12x - 8) \\ 18x {}^{2} \times 12x - 18x {}^{2} \times 8 - 12x \times 12x - 12x( - 8) \\ 216x {}^{ {}^{2} } - 18x {}^{2} \times 8 - 12x \times 12x - 12x \times ( - 8) \\ 216x {}^{3} - 144x {}^{2} - 12x \times 12x - 12x \times ( - 8) \\ 216x {}^{3} - 144x {}^{2} - 12x \times ( - 8) \\ 216x {}^{3} - 144x {}^{2} - 144x {}^{2} + 12x \times 8 \\ 216x {}^{3} - 144x {}^{2} - 144x {}^{2} + 96x \\ 216x {}^{3} - 288x {}^{2} + 96x$
