SUMMARY

When the numerator of a fraction has a higher degree than the denominator, the division process results in a polynomial plus a remainder. This remainder will have a degree smaller than that of the denominator. To verify the correctness of the result, one can multiply the obtained polynomial by the denominator and add the remainder, which should yield the original numerator. This method is essential for simplifying polynomial fractions effectively.

PREREQUISITES
  • Understanding polynomial degrees and their properties
  • Familiarity with polynomial long division
  • Knowledge of verifying polynomial identities
  • Basic arithmetic operations with polynomials
NEXT STEPS
  • Study polynomial long division techniques in detail
  • Practice examples of dividing polynomials with varying degrees
  • Learn how to verify polynomial division results
  • Explore applications of polynomial division in calculus and algebra
USEFUL FOR

Students preparing for mathematics exams, particularly those studying algebra and calculus, as well as educators teaching polynomial operations.

Alright... What are the rules for when the numerator (Top part) of the fraction has a higher degree than the lower part of the fraction.

Something + {*}

... As in what is that SOMETHING based on the numbers?

I have a midterm in like... 50 minutes and this is the only thing I need to know.

Then you divide the two and you have an integer plus the remainder, where the numerator will have a smaller degree than the denominator. The process of dividing may take a little time but it is easy to check if you have the right answer (by simply multiplying your answer with one of the terms). Do you have a specific example?

Since you are talking about a fraction in which the numerator and denominator are polynomials, dividing will give you a polynomial (which corresponds to an integer in "regular" arithmetic) and remainder. The original fraction is equal to that polynomial plus a fraction with the remainder in the numerator, the original denominator as denominator.
