Answer 1

boa noite princesa !!!!

$(9x {}^{6} - 12x {}^{5} + 18x {}^{ {}^{3} } - x {}^{2} ) \div (3x {}^{2} ) \\ \\ \frac{9x {}^{6} - 12x {}^{5} + 18 {}^{3} - x {}^{2} }{3x {}^{2} } \\ \\ \frac{9x {}^{6} - 12x {}^{5} + 5832 - x {}^{2} }{3x {}^{2} } \\ \\ = \frac{9x {}^{6} - 12x {}^{5} - x {}^{2} + 5832}{3x {}^{2} }$

espero que eu tenha conseguido te ajudar...
