Using the quadratic formula, you could say that
the equation have the same relation
of the discriminant
If the form is:
+a%2Ax%5E2+%2B+b%2Ax+%2B+c+
x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+
The discriminant is +b%5E2+-+4%2Aa%2Ac+
If +4%2Aa%2Ac+%3E+b%5E2+, then the roots are
equal and imaginary
Just figure out what a, b, and c
have to be, but make them slightly different
for both equations
