Step 1: Look at formula in formula booklet provided and write out formula.

Formula: (a+b)^{n}= a^{n}+ ^{n}c_{1}a^{n-1}b + ^{n}C_{2}a^{n-1}b^{2}+...+^{n}C_{r}a^{n-r}b^{r }

In this question our a=2 our b=-4x and our n=5

Therefore our first 4 terms are:

4^{5 }+ 5*2 ^{4}*(-4x) + 10

= 32 - 320x +1280x^{2} -2560x^{3}
