Binomial Theorem Problem

[balmy hollow]

I understand how to do A but B is troubling me

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

the answer for b is 4^n somehow

[unreal stirrup]

what if you factored it

[balmy hollow]

yeah thats what im gonna try to do rn

jsut thining of a way to do it

so ig u can pull out 3^n from everything

[balmy hollow]

yeah ive hit a road block

dont think I factored in the right way

let me show u

[unreal stirrup]

oh i was just thinking about factoring the quadratic into its roots

but i dont think it has roots

[balmy hollow]

Oh

[unreal stirrup]

nvm it does have roots

[balmy hollow]

How do u even find them lol

It’s to the power of n

[livid glade]

@balmy hollow try putting x = 1 in A and do binomial theorem on it

[balmy hollow]

well ill just get back to this no?

oh wait

ur right

im so dumb

thank u G
