    [SOLVED] Quadratic expression

    Given: (x^2 + 2ax + 1)^(1/2)

    is it correct to say that x^2 + 2ax + 1 = (x + a)^2 (and make the assumption that a^2 = 1) such that

    (x^2 + 2ax + 1)^(1/2) = |(x + a)| ?

    x^2 + 2ax + 1 = (x + a)^2

    this is not correct for a\ne 1

    (x+a)^2 = x^2 +2ax +a^2
