gamehead200 Posted January 27, 2005 Share Posted January 27, 2005 x(x2+x+1) + 4??There's nothing to solve... Its not an equation, its an expression. You can only simplify it. Link to comment Share on other sites More sharing options...
matrix0978 Posted January 27, 2005 Author Share Posted January 27, 2005 No sure is thats it.... any more? Link to comment Share on other sites More sharing options...

un4given1 Posted January 27, 2005 Share Posted January 27, 2005 Give this a try http://www.webmath.com/anything.htmlAccording to what you said (x^3+x^2+x+4), right? It can't be simplified. Link to comment Share on other sites More sharing options...

phoenix_nf Posted January 27, 2005 Share Posted January 27, 2005 16 - 36 = 25 - 4516 - 36 + (81/4) = 25 - 45 + (81/4)(4^2) - 2 * 4 * (9/2) + [(9/2)^2] = (5^2) - 2 * 5 * (9/2) + [(9/2)^2] [4 - (9/2)]^2 = [5 - (9/2)]^2taking sq. roots on both sides.4 - (9/2) = 5 - (9/2)Adding (9/2) on both sides we get:4 = 5 (find the error) Link to comment Share on other sites More sharing options...
phoenix_nf Posted January 27, 2005 Share Posted January 27, 2005 You can do a similar thing using the equation:4 - 10 = 9 - 15and add (25/4) to both sides.you will get 4 = 5i.e 2 + 2 = 5 (I know its wrong as there IS an error in the equation) Link to comment Share on other sites More sharing options...
XtremeMaC Posted January 27, 2005 Share Posted January 27, 2005 (x3 +x2 +x + 4)if we set it equal to 0 u'd get an answer of -1.74295 other roots are imaginary..@phoenix_nf erm am i missing a post here or something? where did u get those numbers and eequations???

matrix0978 Posted January 27, 2005 Author Share Posted January 27, 2005 haha yeah that was pretty random phoenix. but yeah.Xtreme MaC it cant be solved for an asnwer... it can only be simplified... Link to comment Share on other sites More sharing options...
phoenix_nf Posted January 27, 2005 Share Posted January 27, 2005 yeah XtremeMaC check out page one of this thread (or the post before this post) then you'll get the complete picture. Link to comment Share on other sites More sharing options...
XtremeMaC Posted January 27, 2005 Share Posted January 27, 2005 i only seem to see 2 links and they're not thatanyways if it cannot be solved then its like this:(x2 + 1)(x+1) + 3 or(x2 + 4)(x+1) - 3x or something like that... Link to comment Share on other sites More sharing options...
