    you mean delta? -b+sqrt(delta) / 2a?

    no its binomials in the form of ax^2 - c = 0 or ax^2 = c

    are you referring to trinomials such as x^2+6*x+9 = (x+3)*(x+3)?

    oh, i know, you want a shortcut? ax^2=c, so x^2=c/a, x=±√(c/a)

    for a perfect square trinomial factoring a finding the square root of the trinomial are equivalent because if you square the binomial you get the trinomial as a result, so the binomial is the square root. so yes, that will work.
