Yesterday I found a math document we were given in our 3rd year of High School and there is a question overwhelming me. We have to find the two solutions of [tex](UN)^2=DEUX[/tex] where each different letter has a different integer value and where U!=0 and D!=0 . If I understand correctly I should solve this [tex](10*U+N)^2=1000*D+100*E+10*U+X[/tex] knowing U>2, D!=0 and U!=N!=D!=E!=U!=X (!= meaning isn't equal to) but I have no clue about how to solve it. The only thing I can find is [tex]X=100 U^2+20 UN+N^2-1000 D-100 E-10 U[/tex] and I'm not even sure of this answer... Could anybody give me a hint to the solution?(adsbygoogle = window.adsbygoogle || []).push({});
