what is the discriminant of 2x²-6x=-8 and nature of the roots​

Sagot :

Answer:

Step-by-step explanation:

Determine the nature of the roots using the discriminant.

Δ

>

0

means there are  

2

distinct real roots.

Δ

=

0

means there are  

2

equal real roots, or  

1

distinct real root.

Δ

<

0

means there are no real roots, but  

2

complex roots.

Since the discriminant is less than  

0

there are no real roots. Instead, there are two complex roots.
