Hello!
Very good!
I think you will be interested in what other way you can solve quadratic equations (it can only be used when a is 1):
x^2+4x-12=0
by the theorem, the inverse of Vieta's theorem:
[ x1 + x2 = -b; x1 * x2 = c]
x1+x2 = -4
x1 * x2 = -12
and now we need to find such numbers instead of x1 and x2 so that they fit into both equations : x1=-6 and x2=2
-6+2=-4 (right)
-6*2=-12 (right),
So x1 = -6 and x2=2.
If you figure it out, you can solve the equations in this way in a couple of seconds:)
