    i don't get it i cannot get an integer x x+2 x+4 (x+4)^2=1/4*x^2+1/4*(x+2)^2+12 is what i did and got x^2+14x+6=0

    Let x = first integer then x+1 = second integer and x+2 = third integer ((x+1)/4)^2 +(x^2)/4=(x+2)^2 + 12

    either you typed the question out incorrectly or they didn't check their solutions thoroughly

    My solution was not an integer. I can't work it!

    I too, wonder why such a problem was assigned, sure doesn't reinforce confidence!

    is it possible that they meant 15 and not 12? 15 yields integer solutions
