    if you have a quadratic, first of all "a" cannot be zero, because if "a" is zero it is not a quadratic. so lets eliminate that verbiage. then what this is really saying is, "If a quadratic equation has one zero, compare the signs of the constant and the leading coefficient" if there is one zero you have a perfect square, \[a(x+r)^2\] so they will have the same sign
