Try any number, this equation will obiously always end with x=x - April 18th 2009, 05:07 PMNonCommAlg
clearly every integer is a solution. so i'll assume that let and where then is a solution if and only if:

so hence thus we must have the converse is obviously true, i.e. if then

now, from quadratic formula it's clear that if and only if thus so the general solution of

your equation is:

by the way questions of this type have nothing to do with calculus and they should be posted in high school pre-algebra subforum. - April 18th 2009, 05:31 PMhlolli
