Hi everyone,
I am struggling solving equations like this one for j:
j > (1-ß)* (\[Beta] j (\[Lambda]-1)+z (\[Beta]+\[Beta] (-q)-1)-\[Beta] \[Lambda] w)/((\[Beta]-1) (\[Beta] q+1))
See also the picture for the formula.
Can anyone tell me the correct command to use here?
I haven't been successful trying Solve![enter image description here][1], Reduce and FullSimplify.
Thank you!!

https://community.wolfram.com/groups/-/m/t/2328274
Hello,
I am very new to Wolfram. I have a question I would like to ask. My father, who is a math teacher, has about 18,000 math questions on various math topics that he prepared himself. Most of the correct answers are marked. But there is no documentation on how to solve it. I thought of having Wolfram|Alpha solve these questions. And I've been a member for 1 month. I'm testing the system. My goal is to create an answer document for each question. But since I'm new I don't know how to translate the question into Wolfram Language. If I write an example question, can you guide me on how this could happen?
Sample question:
The equation P(x-2)=(x^2+1).Q(x-1)-x-1 is given. Since the remainder of the polynomial P(x) divided by (x-3) is 20, what is the remainder of the division of the polynomial Q(x) by (x-4)?
How can I write this question to Wolfram Language Notation.
Thanks for all.Umit KARACIVI2021-07-26T22:12:42ZNo solution from RSolve[ ] of two equations?

I know
1. S[n] is Sum[a[k], {k,1,n}]
2. a\[1]==1
I want to get the general solution of a[n] and S[n].
So I tried this one.![enter image description here][2]

But I can't get the answer. What can I do for this problem?Park Seong Hyun2021-07-23T04:04:46ZHow can I Rationalize this?

Hi everyone, I want to make this expression in Wolfram:
![enter image description here][1]
it results from resolve this:
sol=s/.Solve[s^2+(R/L)s+1/(L*C1)==0,s]
it give me this:
![enter image description here][2]
and this what I was trying:
FullSimplify[Expand[Simplify[sol,C1>0]],ExcludedForms->-R/(2L)]
![enter image description here][3]
how can I introduce the "2L" expression on to the root?
