question 3 part(b), how to do it , i know how to do part (a), (c), (d) , but i cant solve this one as the first bracket has power 1

Rearrange the order ie look at \(\displaystyle (1+3x)^6(1-2x)\)

Expend out the first part as far as \(\displaystyle x^3\) and then multiply by the second bracket. Collect together the terms with the same powers of x up to 3.

dint do the (c) also , now I got to know how to do (b), I am going to apply that to come as the latter hastages power 1, and I know that I said I did c (I type that by mistake? sorry)
