If the discriminant of a quadratic equation is equal to 18, which statement describes the roots?

There are two complex roots

There are two real roots

There is one real root,

There is one complex root

Then there are two real roots

Here we have D > 0 i.e Discriminant = 18

Hence, There are two real roots.

Step-by-step explanation:

Given:

To Find :

Which statement describes the roots form all Four options = ?

Solution:

For a Quadratic Equation:

The Discriminant is given as,

So if this Discriminant, say D,

Case 1 :

Then there are two real roots

Here we have D > 0 i.e Discriminant = 18

Hence, There are two real roots.

Case 2 :

If,

Then there are two complex roots.

Case 3 :

If,

Then there are Same and Real roots.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
