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.

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
