Answer 1

i) False, since a quadratic equation has two and only two roots.

ii)False, for example x^2+4=has no real roots.

iii)True,since a quadratic equation has two and only two roots.

iv) True, because every quadratic polynomial has almost two roots.

v) True, since in this case discriminant is always positive

vi)True, since in this case discriminate is always negative.

Answer 2

Step-by-step explanation:

1.False. Every quadratic equation have at least two roots.

2.False.Eevery quadratic have two real roots.

3.True.Every quadratic question have two roots and this is necessary.

4.True. This is necessary that a quadratic eqaution have atmost two roots.

5.True. In this case the Discriminant which is represents by symbol D is positive.

6.True. In this case the Discriminant which is represents by symbol D is negative.
