Find the term independent of x in the expansion of ( (2)/(3) {x}^(2) - (1)/(2x))^(9) ​

Question

Find the term independent of x in the expansion of


`( (2)/(3) {x}^(2) - (1)/(2x))^(9)`
​

Answer 1

Explanation:

`\frac{19683x {}^(18) }{512} - \frac{59049x {}^(15) }{512} + \frac{19683x {}^(12) }{128 } - \frac{15309x {}^(9) }{?128} + \frac{15309x {}^(6) }{256} - \frac{15309x {}^(9) }{128} + \frac{15309x {}^(6) }{?256} - \frac{5103x {}^(3) }{256} + (567)/(128) - \frac{81}{128x {}^(3) } + \frac{27}{512x {}^(6) } - \frac{1}{512x {}^(9) }` it's long there's some calculations in de side hope its helpful
