Discussion Overview

The discussion revolves around the rules for multiplying signs in algebra, particularly in the context of polynomials. Participants seek clarification on the outcomes of multiplying different combinations of positive and negative signs.

Discussion Character

  • Homework-related
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant expresses confusion over the rules for multiplying signs and requests clarification on the outcomes for combinations of signs.
  • Another participant provides a set of rules indicating that +x+ results in +, -X+ results in -, +X- results in -, and -X- results in +.
  • A different participant summarizes the rules stating that same signs yield a positive result and different signs yield a negative result, reiterating the outcomes for each combination.
  • One participant questions the necessity of repeating an answer that has already been provided.
  • Another participant suggests that the timing of responses may explain the repetition, implying that one participant may not have seen the earlier response.

Areas of Agreement / Disagreement

There is some agreement on the rules for multiplying signs, but there is also a contention regarding the repetition of answers and the necessity of providing the same information multiple times.

Contextual Notes

The discussion does not address any potential limitations or assumptions underlying the rules provided, nor does it explore the broader implications of these rules in different contexts.

Hi,

I've tottally confused myself over the mutiplying rules.
Can someone please tell me all the rules

+x+ =
-X+ =
+X- =
-X- =

Because I am stupid and keep messing up my polynomials with them.

look forward to posting many easy questions for you guys, Dam some of this stuff is complicated you guys are good.

Thanks in advanced,
AS.

Same signs= positive,

Different signs= negative:

+x+= +
-x- = +
+x- = -
-x+ = -
 
thanks guys, Knew it was easy :) Helped me though, Even if it was easy.

Appreciate the fast reponse.

I am sorry , but is it really necessary to give the exact same answer that has already been given ? :rolleyes:

making another unnecessry post here but have you checked the times of your response and hallsofivy's? cos it is more than entirely possible he didn't even notice yours.
