sum of all the coefficients of x^5

#### Explanation:

we need to find all the terms with ${x}^{5}$
on doing so
we find only one term $8 C 6 \cdot {x}^{4}$ in the binomial expression so that this when multiplied with $\left(x + 2\right)$ we get a term with ${x}^{5}$
so
answer is : $8 C 6$
hope u find it helpful :)
