If the discrimination of equation is equal to -8, which statement describes the roots ?

see explanation

Step-by-step explanation:

The value of the discriminant informs about the nature of the roots of a quadratic function.

The discriminant Δ = b² - 4ac

• If b² - 4ac > 0, then roots are real and distinct

• If b² - 4ac = 0, then roots are real and equal

• If b² - 4ac < 0, then the roots are not real

Hence for b² - 4ac = - 8, then roots are not real

i could probably can you me with a question of mine?

step-by-step explanation:

the correct answer is 5 6 and 7
