SUMMARY

The equation (x³ + 3x) / (3x² + 1) = 341/91 requires specific methods for resolution, namely Componendo and Dividendo or the k-method. However, the k-method is not applicable due to the absence of proportional relationships. Participants in the discussion emphasized the importance of parentheses and suggested cross-multiplying as an alternative approach. The consensus is that a clear attempt at solving the problem must be demonstrated for effective assistance.

PREREQUISITES
  • Understanding of Componendo and Dividendo methods
  • Familiarity with the k-method in algebra
  • Basic knowledge of rational expressions
  • Ability to apply cross-multiplication in equations
NEXT STEPS
  • Research the application of Componendo and Dividendo in algebraic equations
  • Learn the conditions under which the k-method is applicable
  • Study cross-multiplication techniques for solving rational expressions
  • Explore the significance of parentheses in mathematical expressions
USEFUL FOR

Students and educators in algebra, particularly those tackling rational expressions and seeking to understand advanced solving techniques like Componendo and Dividendo.

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.
