Does not make sense. The equation of the discriminant is $b^2-4ac$, which does not require computing for a square root.
Does not make sense. The equation of the discriminant is $b^2-4ac$, which does not require computing for a square root. For instance, given the quadratic equation: $x^2+x+1=0$, the discriminant can be computed as: $a=1$, $b=1$, $c=1$ $b^2-4ac = 1^2-4(1)(1)$ $b^2-4ac = -3$
