If the discriminant of a quadratie equation is equal to - 8 which statement describes the root

There are two complex too

There are two real roots

There is one real root

There is one complex rool

Answer: A!

there are two complex roots

Step-by-step explanation:

Recall that for a quadratic equation

y = ax² + bx + c

the solution given by the quadratic formula is

x = (-b ± √discriminant) / 2a

if the discriminant is negative, the radical term will become √ (negative number), which we know gives complex solutions. Hence we can eliminate real roots as possible answers.

Also notice that the "±" sign in the quadratic formula means that you will get 2 possible solutions:

x = (-b + √discriminant) / 2a

or

x = (-b - √discriminant) / 2a

Hence we know we will get 2 solutions.

Combining our findings, we can conclude that if the discriminant is negative, we will get 2 complex roots.
