I need The answer to this question

the usual expand result will be 1048576x4 +... is i'm in the right path?

I know the multinomial expansion, but I am not able to use that to find the distinct terms that will be obtained in this expansion. I know that the powers of x will be of the form P=3b+5c where...

the first three terms in the expension of (1-4x)^5 (1+ax+bx^2) are 1-23x+222x^2,Find the value of each of the constants a and b

I'm so bad at these topics ): I need help with this and some explanation, thanks!

I don't have any idea how to do this! i know how to do binomial theorem but not this. I live in the US and taking Ib sl 2 math as a junior.
