    You have to think of this as an algebraic equation.
    Let X stand for the smallest of the three consecutive numbers. Then you can write the equation as:

    434 = x^2 + (x+1)^2 + (x+2)^2

    This will simplify into finding the where this polynomial (on the right) will equal 434 - this can be done in multiple ways...

    Hope this helps.

    If that's it... well, have you simplified the equation?
