The discriminant of 2x² - 4x + 3 = 0 is:

If one root of a quadratic equation is complex, the other root must be its conjugate.

The condition that the roots of ax²+bx+c=0 are reciprocals of each other is $ac = b$ (True/1/False/0).

If the roots of x² - px + 6 = 0 are in the ratio 2:3, then p =

If α and β are roots of ax²+bx+c=0, then α + β =

If discriminant D > 0, the roots of ax²+bx+c=0 are real and unequal.
