Discussion Overview

The discussion revolves around expanding the binomial expression (a+b) raised to various powers, specifically up to the 15th power, as part of a homework assignment. The focus includes methods for expansion and potential shortcuts, as well as the application of Newton's binomial formula.

Discussion Character

  • Homework-related
  • Mathematical reasoning
  • Technical explanation

Main Points Raised

  • One participant requests a quick method to expand (a+b) raised to the 15th power, expressing urgency due to an impending deadline.
  • Another participant suggests starting with the basic expansion of (a+b)² and using multiplication properties to derive further expansions.
  • A third participant provides the expanded form of (a+b)² as a² + 2ab + b² and questions whether the focus is on (a+b)² raised to the 15th power or (a+b) raised to the 15th power.
  • One participant mentions that the teacher is likely testing the understanding of Newton's binomial formula, implying its relevance to the task at hand.

Areas of Agreement / Disagreement

Participants generally agree that the task involves the application of the binomial expansion, but there is no consensus on the specific approach or method to be used. The discussion remains unresolved regarding the most efficient way to complete the assignment.

Contextual Notes

There are assumptions about the participant's familiarity with binomial expansion and Newton's binomial formula, which may not be universally shared. The discussion does not clarify the exact requirements of the homework assignment.

Can Someone Plz Answer Asap!

My teacher gave me homework and i got to convert for ex. (a+b)squared=a squared+ab+b squared, i got to do this up until to the 15th power. Please anyone have an ez way to do this or a shortcut. PLZ REPLY MY SPRING BREAK IS ALMOST OVER I HAVE LIKE 3 DAYS TO DO THIS

What is your question? You need to expand

[tex](a+b)^2[/tex]

?

Just write it as

[tex](a+b)(a+b)[/tex]

and use the properties of multiplication...

[tex](a+b)^{2}=a^{2}+2ab+b^{2}[/tex] !

Now,are u interested in that

[tex]\left[(a+b)^{2}\right]^{15}=(a+b)^{30}[/tex]

,or in that

[tex](a+b)^{15}[/tex]

Do you know something about the Newton's binomial formula ...?

kollo3:
You know of Newton's binomial formula.
Your teacher is testing you whether you understand how to apply that formula or not.
