Homework Help Overview

The discussion revolves around solving the equation (x³ + 3x) / (3x² + 1) = 341/91 using specific methods known as Componendo and Dividendo, as well as the k-method. Participants express challenges in applying these methods to arrive at a solution.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants discuss the importance of parentheses in the equation and the necessity of using Componendo and Dividendo or the k-method exclusively. Some question the understanding of these methods among participants.

Discussion Status

There is ongoing exploration of the problem, with some participants offering guidance on applying Componendo and Dividendo again. Others express frustration with their attempts and seek further assistance, indicating a lack of consensus on the best approach.

Contextual Notes

Some participants note that they are not allowed to use general algebraic methods, which may limit their problem-solving strategies. There is also uncertainty about the definitions and applications of the methods mentioned.

Please solve this equation :

x3+3x/3x2+1 = 341/91

I applied Componendo and Dividendo, then k-method but could not solve this question. Please help me.

Do you mean: (x3+3x)/(3x2+1) = 341/91 ?

Parentheses are important.
 
yes.
 
Did you try applying the rules of algebra?
 
no, i must use either componendo and dividendo or k-method. No algebra at all.

I doubt that many of us here even know what "componendo and dividendo" mean or what "k-method" means.

The first two are apparently Spanish or maybe Portuguese for combining and dividing.
 
physics kiddy,
Are you trying to solve for x, or are you substituting a value for x in order to evaluate the rational expression?

Hiii physics kiddy !

Try applying componendo and dividendo once more. I will guide you. :wink:

k-method cannot work here because there are no proportional relation given.
If there are relations like a,b,c and d are in continued proportion , then k-method can be applied.

You can even try cross-multiplying.
:wink:

Please solve this question. I am tired of using componendo and dividendo but all my efforts go useless. I can't go any further. It would be very kind of you if you solve the question. Thanks again for the help.

You need to show an attempt at the problem. Show us what you've tried.
