Anderson uses the discriminant to correctly find the number of real solutions of the quadratic equation x2 + 4x + 8 = 0. which explanation could anderson provide?

the equation has no real number solutions because the discriminant is 0.

the equation has one real number solution because the discriminant is 0.

the equation has no real number solutions because the discriminant is less than 0.

the equation has two real number solutions because the discriminant is greater than 0.

Option 3rd is correct

The equation has no real number solutions because the discriminant is less than 0

Step-by-step explanation:

Discriminant(D)of a quadratic equation is given by:

As per the statement:

Anderson uses the discriminant to correctly find the number of real solutions of the quadratic equation:

On comparing the given equation with  we have;

a = 1, b = 4 and c = 8

then;

⇒

By definition;

Discriminant is less than 0

equation does not have real roots

Therefore, the equation has no real number solutions because the discriminant is less than 0

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
