To prove that there is no term involving \( x^6 \) in the expansion of \( (2x^2 - \frac{3}{x})^{11} \), we can follow these steps: ### Step 1: Identify the general term in the binomial expansion The general term (the \( (r+1) \)-th term) in the expansion of \( (a + b)^n \) is given by: \[ T_{r+1} = \binom{n}{r} a^{n-r} b^r \] For our expression, \( a = 2x^2 \), \( b = -\frac{3}{x} \), and \( n = 11 \). ...
