Vedclass · Answer

(C) The binomial expansion for $(1 + z)^n$ is given by $1 + nz + \frac{n(n-1)}{2!}z^2 + \frac{n(n-1)(n-2)}{3!}z^3 + \dots$Here,$n = \frac{3}{2}$ and $z = -x$.Substituting these values:Term $1$: $1$Term $2$: $\frac{3}{2}(-x) = -\frac{3}{2}x$Term $3$: $\frac{\frac{3}{2}(\frac{3}{2}-1)}{2!}(-x)^2 = \frac{\frac{3}{2} \cdot \frac{1}{2}}{2}x^2 = \frac{3}{8}x^2$Term $4$: $\frac{\frac{3}{2}(\frac{3}{2}-1)(\frac{3}{2}-2)}{3!}(-x)^3 = \frac{\frac{3}{2} \cdot \frac{1}{2} \cdot (-\frac{1}{2})}{6}(-x)^3 = \frac{-\frac{3}{8}}{6}(-x^3) = \frac{3}{48}x^3 = \frac{1}{16}x^3$Thus,the first four terms are $1 - \frac{3}{2}x + \frac{3}{8}x^2 + \frac{1}{16}x^3$.
