Solve any quadratic equation, find Discriminant and all roots of equation.
Its square is widely called the Discriminant,
though some sources call the Vandermonde polynomial itself the Discriminant.
The second approach, called Discriminant validation, is that the technique should not
measure any characteristics with which theoretically there should be no correlation.
In conclusion, the scale developed in this study demonstrated strong psychometric, structure,
convergent, and Discriminant validity, which is consistent with Andreassen et al. 's(2015)
findings”.
Solution: False, since the Discriminant in this case is-
4ac which can still be nonnegative if a and c are of opposite signs or if one of a or c is zero.
The maturation of Marsala is a very important Discriminant and is applied above all to the Virgo type(at least 5 years),
while for the Conciato it is lower(it never exceeds 4 years).
This tells us that if the stainless steel band is weak magnetic or completely non- magnetic, it should be identified as 304 or 316 materials; If the magnetic properties of carbon steel,
show strong magnetic, because the Discriminant is not 304 material.
