Snoex Posted May 31, 2009 Report Share Posted May 31, 2009 Is the explanation mark suppose to go on the other side of the 4? Link to comment Share on other sites More sharing options...
Sid. Posted May 31, 2009 Report Share Posted May 31, 2009 I think she meant 14 not !4. And i have a thought on how to do this, but to clarify your supposed to find X right? Link to comment Share on other sites More sharing options...
Snoex Posted May 31, 2009 Report Share Posted May 31, 2009 Ah. you're probably right Sid. Yeah, well she didn't state otherwise so I would assume we find X Link to comment Share on other sites More sharing options...
Felix Culpa Posted May 31, 2009 Report Share Posted May 31, 2009 I think she meant 14 not !4. And i have a thought on how to do this' date=' but to clarify your supposed to find X right? [/quote']Or that is the incorrect way of putting 4! which means 4 factorial. Link to comment Share on other sites More sharing options...
Snoex Posted May 31, 2009 Report Share Posted May 31, 2009 OneWord: That's what I thought too then Sid said the ! could be 1, but ~Chidori- Kun accidentally put the !. The obvious choices that we have are a. wait for Chidori to clarify b. Do the equation two times using both 14 and 4! c. give up on the problem.

OhHerro Posted June 1, 2009 Report Share Posted June 1, 2009 5z -7 = 13 - z (3z - 1)(6z + 7) 5z - 7 = 13 - z(18z^2 + 21z - 6z - 7) 5z - 7 = 13 - z(18z^2 + 15z - 7) 5z - 7 = 13 - 13z^3 +15z^2 -7z 13z^3 - 15z^2 + 12z = 20. Not factorable... Assuming that's how you wanted it, pretty easy. Link to comment Share on other sites More sharing options...
