    That's because

    (n + 1)^2 = n^2 + 2n + 1 = n^2 + n + n +1 = n^2 + [n + (n + 1)]

    Brilliant and easy to understand, you have the makings of a math tutor. Thank you.

    very cool, but I wanted to tell you that you mis-titled this. This would be a method of finding squares, not square roots. squares are as you show 26^2 (26*26)but square roots would be ___
    \/26
    if that doesn't show up right, then square roots are what number squared equals this number, not what is this number squared.
